FYI, here is a quick and clean/safe performance improvement for grep -i.
I expect to push this commit right after the upcoming bug-fix release.
Currently, this optimization is enabled when the search string is
ASCII and contains neither of '\' (backslash) nor '['.  I expect to
eliminate the latter two constraints in a follow-on commit including
tests to exercise all of the corner cases.

Happy holidays,
Jim
