[-- Attachment #1.1: Type: text/plain, Size: 995 bytes --]

The attached patch series is mostly aimed at removing XEmacs-specific code,
which is not needed, since our version of ispell.el has been part of GNU
Emacs for some time, and is not imported from upstream (the most recent
upstream release was over 20 years ago). Similarly, some workarounds for
older versions of GNU Emacs are removed (since ispell.el is not distributed
separately); in any case, most of the workarounds seem to pertain to GNU
Emacs pre-version 21.

The pre-VCS change history is also removed by the patch.

This clean-up series is aimed at making things neat before I add enchant
support (bug #17742), which will be a very simple change.

One patch also removes the pre-GNU Emacs maintainer information, so that
attentive users (who read the source!) do not mistakenly try to file bug
reports &c. with the original upstream.

I have supplied the patches as a series for ease of reading, but could
compress them if desired for installation in Emacs git.

* lisp/textmodes/ispell.el (Commentary): Remove original maintainer
  details, as Emacs version, bug report address and so forth should be
  used instead for this version.  Remove in-line change history; use
  git instead.

document precise personal wordlist filenames for only two supported
spelling checkers, simply say that the default personal dictionary
depends on the chosen spelling checker.  The user can check the
spelling checker’s documentation if necessary.  This is simpler, and
works for other supported (and future, or unknown) spelling checkers.
