Re: grep-2.6 is imminent: pending patches, bug reports?

Hi Jim.

Has anyone looked at issues with dfa.c?  There is a difference in
how dfa handles   x{0}   from how regex handles it; dfa, IIRC, treats
it as x{1}. Gawk checks for this and doesn't use dfa in such a case,
but it'd be nice if it were fixed.

There may be other fixes in the gawk dfa.[ch] that should be
looked at too, but I don't recall what off the top of my head.

There is the general issue that grep dfa and gawk dfa have diverged.
It'd be nice if they could be brought back together.

Thanks,

Arnold
