bug#5584: 23.1.90; Setting enable-recursive-minibuffers to non-nil ignor


From: Brent Goodrick
Subject: bug#5584: 23.1.90; Setting enable-recursive-minibuffers to non-nil ignores minibuffer history
Date: Tue, 16 Feb 2010 06:55:57 -0800

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

Starting from `emacs -Q' off of a freshly built Emacs from CVS on a
32-bit RHEL5 system (but the system doesn't matter since I've seen this
on Windows and 64-bit Linux):

1. Switch into the *scratch* buffer
2. Type the following:
     (setq enable-recursive-minibuffers t)
   Hit Control-J to evaluate it
3. Type M-x flush-lines RET
4. While the minibuffer is active waiting for the string for
   `flush-lines', type M-: (or its equivalent of `M-x eval-expression')
5. Type (insert "flubber") RET
6. Type RET to complete the flush-lines
7. Do steps 3 and 4 again.
8. Type M-p and notice the error message stating no previous history element,
   which is incorrect.

The reason this is an issue is that I find myself constantly needing
to type in a regular expression using `rx' syntax via

  (insert (rx ....))

and not being able to get back to that history element is a burden for 
complex rx expressions.  Not using `' seems to fix it, but then I give
up recursive minibuffers which I find very handy.

Thanks!
