Re: "^.*$" not matching in sed with certain characters?

[arnold]

This issue may exist in gawk as well.  It would be nice to isolate
it further, on two levels.

1. Is it the dfa matcher that is interpreting things differently from
   the regex routines?  IIRC sed doesn't use dfa.

2. If it is the regex routines in both cases, which syntax bit is
   causing the difference in interpretation?

3. If it is a dfa vs. regex issue then someone should decide how to
   bring the two matchers back into consistency with each other.

Thanks,
