annotate src/debug.c @ 5649:d026b665014f
Actually obey POSIX rules in #'posix-string-match, don't ignore them.
src/ChangeLog addition:
2012-04-25 Aidan Kehoe <kehoea@parhasard.net>
* search.c (string_match_1): Actually use the POSIX argument here,
pass it to compile_pattern(). Thank you for the bug report, Ilya
Shlyakhter!
tests/ChangeLog addition:
2012-04-25 Aidan Kehoe <kehoea@parhasard.net>
* automated/regexp-tests.el: Check that #'posix-string-match
actually returns the longest match; thank you Ilya Shlyakhter in
jn1j8t$ujq$1@dough.gmane.org !
