[PATCH 2/2] The core GIT tests: recent additions and fixes.

This set of scripts are designed to test the features and fixes
we recently added to core GIT.  The convention to call test
helper function has been changed during the framework cleanup
(take two), and these tests have been updated to use the cleaned
up test-lib.sh interface.

Signed-off-by: Junio C Hamano <junkio@cox.net>

Note that this does not include the t2000-diff.sh script since it
tests a patch which was not applied yet.
