[Chicago-talk] /i resets $1 on failed matches?

Obviously someone out there needs to see Andy's command line talk
before using 'cat' with 'perl -n'...

Regex bug. Damian's attempt to shoehorn parts of the P6 regex
behavior into 5.8 resulted in quite a few bug reports (5.8.5,
comming out this week, should offer an improvement). Aside
from that there is no reason /i should affect the outcome of
the regex match variables. /g and /m can do things based on
finding repeating matches throughout the process but those
are related to iterative behavior of the match, not how the
individual matches are arrived at.
