M-%, in query-replace, offers less-than-ideal default replacement text

[Eric Hanchrow]

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.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

* start emacs with "emacs -Q -nw"

* in the *scratch* buffer, prepare two lines of "foo" as test data by
  typing F O O RET F O O RET.

* M-< C-s foo M-% bar RET SPC q

Thus we have replaced the first "foo" with "bar".  So far, so good.
However:

* C-a C-s foo M-% 

Note that the prompt reads "Query replace foo with:", offering no
default text.  Nothing wrong with that ... however, now hit M-p to see
the most-recent value in the command history.  Here's the problem: I'd
expect to see "bar" here, but instead I see "foo".  I have to hit M-p
a second time to see "bar".

I don't think it makes sense to see "foo" here, since "foo" was never
used as replacement text.

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/local/src/emacs-cvs/etc/DEBUG for instructions.
