Subject: mentioning variable aliases in `describe-variable'
Date: Wed, 10 Jul 2002 10:42:47 +0100 [thread overview]
Message-ID: <E17SDzj-0000sL-00@bundalo.shootybangbang.com> (raw)
I think it would be nice to mention when a variable is an alias in
`describe-variable'. What do people think ?
2002-07-10 John Paul Wallington <jpw@shootybangbang.com>
* help-fns.el (describe-variable): Mention if the variable is an
alias.
