abbrev-mode - toggle-abbrev-mode

[Andreas Röhler]

It seems as `toggle-abbrev-mode' in GNU Emacs and
`abbrev-mode' in XEmacs are reciprocal.

As I'm going to adapt my GNU Emacs Lisp stuff to run at
XEmacs too, I would like to keep the diffs as small as
possible.

I'm not going to say, abbrev-mode in XEmacs isn't as
good as in GNU, rather I'm campaigning to take the
X-way there.

However, in cases were commands only differ by name,
what about to give RMS the honour and simply follow GNU
convention?

Thanks all
