lgrep/rgrep not asking to save buffers

[Tom Tromey]

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 bug-gnu-emacs@gnu.org 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:


I notice that lgrep and rgrep do not offer to save buffers.
This is different from other search and compilation commands.
This means that sometimes the results are incorrect.

Ideally these would only offer to save files that might actually be
matched by the command -- i.e., filtering buffers based on file
extension and directory.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/share/emacs/22.1/etc/DEBUG for instructions.
