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, Arnold
