;;; Commentary:
;;{{{ Introduction
;; Preface
;;
;; This package provides a minor mode, compatible with all major
;; editing modes, for folding (hiding) parts of the edited text or
;; program.
;;
;; Folding mode handles a document as a tree, where each branch
;; is bounded by special markers `{{{' and `}}}'. A branch can be
;; placed inside another branch, creating a complete hierarchical
;; structure.
;;
;; Folding mode can CLOSE a fold, leaving only the initial `{{{'
;; and possibly a comment visible.
;;
;; It can also ENTER a fold, which means that only the current
;; fold will be visible, all text above `{{{' and below `}}}'
;; will be invisible.
;;
;; Please note, that the maintainers do not recommend to use only
;; folding for you your code layout and navigation. Folding.el is
;; on its best when it can "chunk" large sections of code inside
;; folds. The larger the chunks, the more the usability of
;; folding will increase. Folding.el is not meant to hide
;; individual functions: you may be better served by hideshow.el
;; or imenu.el (which can parse the function indexes)
;;}}}
;;{{{ Installation
;; Installation
;;
;; To install Folding mode, put this file (folding.el) on your
;; Emacs `load-path' (or extend the load path to include the
;; directory containing this file) and optionally byte compile it.
;;
;; The best way to install folding is the autoload installation,
;; so that folding is loaded into your emacs only when you turn on
;; `folding-mode'. This statement speeds up loading your .emacs
;;
;; (autoload 'folding-mode "folding" "Folding mode" t)
;; (autoload 'turn-off-folding-mode "folding" "Folding mode" t)
;; (autoload 'turn-on-folding-mode "folding" "Folding mode" t)
;;
;; But if you always use folding, then perhaps you want more
;; traditional installation. Here Folding mode starts
;; automatically when you load a folded file.
;;
;; ;; (setq folding-default-keys-function
;; ;; 'folding-bind-backward-compatible-keys)
;;
;; (if (load "folding" 'nomessage 'noerror)
;; (folding-mode-add-find-file-hook))
;;
;; Folding uses a keymap which conforms with the new Emacs
;; (started 19.29) style. The key bindings are prefixed with
;; "C-c#" instead of old "C-c". To use the old keyboard bindings,
;; uncomment the lines in the the above installation example
;;
;; The same folding marks can be used in `vim' editor command
;; "set fdm=marker".
;;
;; Uninstallation
;;
;; To remove folding, call `M-x' `folding-uninstall'.
;;
;; To read the manual
;;
;; At any point you can reach the manual with `M-x'
;; `finder-commentary' RET folding RET.
;;}}}
;;{{{ DOCUMENTATION
;; Compatibility
;;
;; Folding supports following Emacs flavors:
;;
;; Unix Emacs 19.28+ and Win32 Emacs 19.34+
;; Unix XEmacs 19.14+ and Win32 XEmacs 21.0+
;;
;; Compatibility not for old NT Emacs releases
;;
;; NOTE: folding version starting from 2.47 gets around this bug
;; by using adviced kill/yank functions. The advice functions are
;; only instantiated under problematic NT Emacs versions.
;;
;; Windows NT/9x 19.34 - 20.3.1 (i386-*-nt4.0) versions contained
;; a bug which affected using folding. At the time the bug was
;; reported by Trey Jackson <trey A T cs berkeley edu>
;;
;; If you kill folded area and yank it back, the ^M marks are
;; removed for some reason.
;;
;; Before kill
;; packages or modes
;;
;; Folding.el was designed tofor big files. Sometimes people misunderstand the
;; better job. Trying to wrap
;; individual functions insis not where folding is
;; it's best. Grouping several f logical fold-block
;; in the other is. So, to choose a our need,
;; here are some suggestions,:
;;
;; o Naation of imenu.el, speedbar.el and
;; hideshow.el
;; ng.el
;; o For text, `outline-mode' is more non-intrusive.
;; Look at Emacs NEWS file (`C-x' `n') and you can se: `M-x' `folding-mode'
;; `RET'. The mode line should cont When loading a document containing fold marks, Folding mode ised. For example when

;; Folding and outline modes
;;
;ame as Outline mode, a major and
;; minor mode which is pahe Emacs distribution. The two
;; packages do, however, re other very much. The main
;; differences between the twore:
;;
;; o Folding mode uses explicit marks, `{{{' and `}}}', to
;; mark the beginning and the end of a branch.
;; Outline, on the other other hand, tries to use already
;; existing marks, like the `\section' string in a TeX
;; document.
;;
;; o Outline mode has no end marker which means that it is
;; impossible for text to follow a sub-branch.
;;
;; o Folding mode use the same markers for branches on all depths,
;; Outline mode requires that marks should be longer the
;; further, down in the tree you go, e.g `\chap', \section',
;; `\subsection', `\subsubsection'. This is needed to
;; distinguish the next mark at the current or higher levels
;; from a sub-branch, a problem caused by the lack of
;; end-markers.
;;
;; o Folding mode has mouse suppoyou can navigate through a

;; It is not likely that any of this will come true coning
;; the time required to rewrite the core of the package. Since
;; the package, in it's current state, is much more powerful than
;; the original, it would be appropriate to write such package
;; from scratch instead of doing surgery on this one.
;;}}}
;;{{{ Customization
;; Customization: general
;;
;; The behavior of Folding mode is controlled mainly by a set of
;; Emacs Lisp variables. This section will discuss the most
;; useful ones, for more details please see the code. The
;; descriptions below assumes that you know a bit about how to
;; use simple Emacs Lisp and kt ~/.emacs, your
;; init file.
;;
;; Customization: hooks a
;; function doing the customization. The function is the see
;; the example section below.) The following hooks lding mode is activated.
;; o `<major mode>-folding-hookjor
;; mode set to <major mode>. (e.g. When editing C the hook `c-mode-folding-hook' is called.)
;; o `fol Called when folding mode is loaded into Emacs.
;;
;; C it is used by outline-minor-mode. It is not likely that fe try to use folding and outline at the same time.
;;
;; Ho. The
;; variable `folding-default-keys-function' specifiing line to your
;; init file:
;;
;; (setq folding-default-keys-function
;; 'folding-bind-backward-compatible-keys)
;;
;; To define keys similar to the keys used by Outline mode, use:
;;
;; (setq folding-defaut-keys-function
;; 'folding-bind-outline-compati-keys)
;;
;; Customization: adding new major modes
;;
;; To add fold marks for a new major mode, use the function
;; `folding-add-to-marks-list'. The command also replaces
;; existing marks. An example:
;;
;; (folding-add-to-marks-list
;; 'c-mode "/* {{{ " "/* }}} */" " */" t)
;;
; Customization: ISearch
;;
;; If you don't like the extension folding.el applies to isearch,
;; set the variable `folding-isearch-install' to nil before
;; loading this pacndard
;; ones, you can do like this:
;;
;; (setqs-function

Answer 1

There's at least one error in the code in your .emacs, here:
; to enable folding mode
(load "folding" 'nomessage 'noerror)
(folding-mode-add-find-file-hook)t
That t is a syntax error as it stands. Might just be a type frpom cut and paste though.
On the error, Trey'd right, and in fact I think I know what the error probably is: somehow the trailing quote mark in the string
"Latest folding is available at http://cvs.xemacs.org/-xemacs-p
has gone missing. From the two of these issues, I suspect your source is corrupt.

Answer 2

It looks like your folding file /Users/Masi/.lisp/folding.el has a problem, we'd need to see the contents of that to determine the error. The reason I say so is that the stack trace goes through a call to load-with-code-conversion - which shows the folding.el file being loaded.
If you take a look at the latest version, found here (version 3.42), the line that begins
(defvar folding-package-url...
is properly formed. However, the stack trace in yours looks like there is some lisp code that somehow made it into the string. Namely the:
