Re: [PATCH 00/10] pickaxe: honor -i when used with -S and --pickaxe-regex; cleanups

René Scharfe [off-list ref] writes:

This series allows the options -i/--regexp-ignore-case, --pickaxe-regex,
and -S to be used together and work as expected to perform a pickaxe
search using case-insensitive regular expression matching.  Its first
half refactors the test script and extends test coverage a bit while
we're at it.  The actual change is in the sixth patch.  It enables the
two following cleanups.  The last two patches are independent simple
cleanups.

Very nice.  Thanks.
