Fine with me.

LGTM, a few minor comments below.

Please leave a blank before the left parenthesis where indicated.
Also, another blank between the right parenthesis and the following
question mark.
> + STRINGP (obj)? SDATA (obj) : \
Likewise here.

Not "by GC", but "as a side effect of calling malloc". Maybe it's a
good idea to also mention ralloc.c here.

I'm not sure the reader will understand the significance of calling
re_match_2 only once. It would be good to clarify the comment.
Otherwise, I think this should go in.
Thanks!
