Since 23fc63bf8f (make tests ignorable with "make -i", 2005-11-08), each
test file defines a target in the test Makefile, such that one can
invoke:

	make *checkout*

to run all tests with 'checkout' in their filename. This is useful to
run a subset of tests when you have a good idea of what part of the code
is touched by the changes your are testing.

Document that in t/README to help new (or more seasoned) contributors
that might not be aware.

 Since the tests all output TAP (see https://testanything.org) they can
 be run with any TAP harness. Here's an example of parallel testing
 powered by a recent version of prove(1):
