libc/regex: fix two buffer underruns.
Fix some rather complex regex issues found on OpenBSD as part of some
ongoing work to fix a sed(1) bug.
Curiously the OpenBSD tests don't trigger segfaults on FreeBSD but the
bugs were confirmed by running a port of FreeBSD's regex under OpenBSD's
malloc. Huge thanks to Ingo for confirming the behavior.
