[PATCH 07/12] grep & rev-list doc: stop promising libpcre for --perl-regexp

Stop promising in our grep & rev-list options documentation that we're always going to be using libpcre when given the --perl-regexp option.

Instead talk about using "Perl-compatible regular expressions" and using "the PCRE library". Saying "libpcre" strongly suggests that we might be talking about libpcre.so, which is always going to be v1.

Not only do does the documentation now align more clearly with future plans, but it should be more easily readable to the layman.

This is for preparation for libpcre2 support, which in the future may be powering the --perl-regexp option by default, depending on how Git is compiled.
