Subject: [PATCH] git-grep: Update tests (mainly for -P)
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Add few more tests for "-P/--perl-regexp" option of "git grep".

While at it, add some generic tests for grep.extendedRegexp config option,
for detecting invalid regexep and check if "last one wins" rule works for
selecting regexp type.
