Thomas Dickey implemented POSIX-style character classes among other
things in mawk 1.3.3-20090727. The CVS revision number increased by
more than one, so maybe Thomas could provide a more minimal patch.
The unsplit patch is at
http://git.debian.org/?p=collab-maint/mawk.git;a=commitdiff;h=cb2ac5fd#patch33
That patch breaks regexps such as [[]. Fixed by
http://git.debian.org/?p=collab-maint/mawk.git;a=commitdiff;h=2c33a83f
(collect_RE(), do_class(): handle [ in character classes properly,
2010-01-24), fix applied upstream in mawk 1.3.4-20100131.
If you would like a minimal diff for character class support, I can
work on it, but no promises that I’ll have time soon. The above
should give enough pointers that anyone who is interested could make
progress...
Cheers,
Jonathan
