Re: [PATCH 21/25] pickaxe: use PCREv2 for -G and -S

There's a bug here where now different things are dispatched to either
the -S or -G codepath wrongly, I've fixed it in my local version.

Anyway, it's interesting between this and the -U0 change that we have
little/no coverage for some/all of this. I'm trying to address that in
preceding patches in v2.

Back when I did the original -S<fixed>, we weren't as focused on
good test coverage as we are now.  We may have added a lot more by
the time when we introduced -G and -S<regexp>, but your effort that
resulted in noticing the lack of basic coverage and rectifying the
situation is very much appreciated.

Thanks.
