This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

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':

M-x query-replace is case insensitive by default.  You may sometimes
want to replace a string with another differing only in case, for
example changing 'aaa' to 'Aaa'.  But query-replace prompts for all
cases where a case-insensitive match for 'aaa' is found, even those that
already equal the destination string.

Here are the keypresses starting from 'emacs -Q' to reproduce:

a a a RET A a a RET ESC O A ESC O A ESC % a a a RET
A a a RET y

I suggest that if the search and replacement strings differ only in
case, then Emacs should prompt only where there is a real choice to be
made.  When the match of 'Aaa' is highlighted it makes no difference
whether you answer y or n; so Emacs should not waste the user's time
asking.

This does mean that the matches highlighted by query-replace differ from
those you would find with a normal case insensitive search, in these
specific circumstances where the search and replacement strings differ
only in case.  I think that is a fair tradeoff.


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'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.5/etc/DEBUG.
