The reason I've included them in patch is that I've learned about Emacs's
add-change-log-entry command, which conveniently adds entry to existing
file ;-) So, in case if there are several ChangeLog files in patch, I should
put those entries separately, and indicate which file each entry goes to,
right?

So, what's the point of mi2 tests at all?
In any case, there's revised patch:
./Changelog:
2006-05-05 Vladimir Prus <ghost@lvk.cs.msu.su>
* mi/mi-cmd-stack.c (mi_cmd_stack_list_frames): Don't emit error
if high requested frame number is larger then number of available
frames.
doc/ChangeLog
2006-05-05 Vladimir Prus <ghost@lvk.cs.msu.su>
* gdb.texinfo (GDB/MI Stack Manipulation): Mention that
-stack-list-locals HIGH_FRAME argument can be larger then the
actual number of frames.
testsuite/ChangeLog
2006-05-05 Vladimir Prus <ghost@lvk.cs.msu.su>
* gdb.mi/mi-stack.exp (test_stack_frame_listing): Test that
HIGH_FRAME argument to -stack-list-locals can be larger than
the number of frames.
