Subject: [PATCH] grep -P: add tests for matching ^ and $
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Earlier, fba4f1 (grep -P: Fix matching ^ and $) fixed an ancient bug.  Add
some tests to protect the change from future breakages; a slightly broken
version of this was a part of the originally submitted patch.
