Re: Defcustom write-file-functions and write-contents-functions?

[Luc Teirlinck <teirllm@dms.auburn.edu>]

Avtually, in my previous files.texi diff, I forgot to make a relevant
change: make the defvar's for `before-save-hook' and `after-save-hook'
into defopt's:

  This works just like @code{write-file-functions}, but it is intended for
  hooks that pertain to the contents of the file, as opposed to hooks that
  pertain to where the file came from.  Such hooks are usually set up by
! major modes, as buffer-local bindings for this variable.
  
  This variable automatically becomes buffer-local whenever it is set;
! switching to a new major mode always resets this variable.
  @end defvar
  
! @defvar before-save-hook
! This normal hook runs before a buffer has been saved in its visited
! file.  One use of this hook is for the Copyright package; it uses this
! hook to make sure the file has the current year in the copyright
! header.
! @end defvar
  
  @c Emacs 19 feature
! @defvar after-save-hook
  This normal hook runs after a buffer has been saved in its visited file.
  One use of this hook is in Fast Lock mode; it uses this hook to save the
  highlighting information in a cache file.
! @end defvar
  
  @defvar file-precious-flag
  If this variable is non-@code{nil}, then @code{save-buffer} protects
