grep -P: Fix matching ^ and $
When "git grep" is run with -P/--perl-regexp, it doesn't match ^ and $ at
the beginning/end of the line. This is because PCRE normally matches ^
and $ at the beginning/end of the whole text, not for each line, and "git
grep" passes a large chunk of text (possibly containing many lines) to
pcre_exec() and then splits the text into lines.
This makes "git grep -P" behave differently from "git grep -E" and also
from "grep -P" and "pcregrep":
$ cat file
a
b
$ git grep --no-index -P '^ ' file
$ git grep --no-index -E '^ ' file
file: b
$ grep -c -P '^ ' file
b
$ pcregrep -c '^ ' file
b
