bug#25555: 25.1.91; smerge-keep-current -vs- empty change

[Tom Tromey <tom@tromey.com>]

I'm using smerge to fix up some files after a rebase.

I have a change that looks like:

<<<<<<< 9f33cac3f07100fe4835ade224e10f3ce58affdc
=======
... lots of stuff here
>>>>>>> Bug 1060419 - make log_print use Printf.h, r?froydnj


I want to use smerge to keep the original change -- which is empty.
However C-c ^ RET (aka smerge-keep-current) on either the "<<<"
or "===" line says:

smerge-keep-current: Not inside a version

Tom
