Subject: bug#4209: 23.1; Emacs 23.1 regression in re-search-forward
Date: Tue, 1 Dec 2009 16:21:07 -0800 [thread overview]
Message-ID: <d791b8790912011621i481383e5pd8976c7a4d897633@mail.gmail.com> (raw)
This is a stab in the dark, but the patch below corrects this issue for me:
$ ./retest.sh
looking-at: t
re-search-forward: 9
I don't see any reason this should cause regressions (searching
forward 0 steps seems to me it should be the same as searching
backward 0 steps), but I've only casually looked over regex.c.
