To me the description in files.texi of write-contents-functions does not 
make much sense.
I suggest the chances attached.
Do you agree?

  @defvar write-contents-functions
  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.  If any of the
! functions in this hook returns non-@code{nil}, @code{write-file-functions}
! is not run.
  
  This variable automatically becomes buffer-local whenever it is set;
  switching to a new major mode always resets this variable, but
