In tests, call test_cmp rather than raw diff where possible (i.e. if the output does not go to a pipe), to allow the use of, say, 'cmp' when the default 'diff -u' is not compatible with a vendor diff. When that is not possible, use $DIFF, as set in GIT-BUILD-OPTIONS. Signed-off-by: Gary V. Vaughan <gary@thewrittenword.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
