[PATCH] git-grep: Update tests (mainly for -P)

Michał Kiedrowicz· May 22, 2011, 11:37 UTC · lore

This patch adds few more tests to git-grep concerning the -P/--perl-regexp option.

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.

This is the promised update to tests and is meant to be applied on top of
mk/grep-pcre.

At some point it would be a good idea to clean these up to use either cascading && or

	cat >ab <<\-EOF &&
        ...
        EOF

everywhere.
