examples: a test, for rev-list
examples: a test, for rev-list

This test file could probably be improved by a framework like
the one in git.git:t/, or by using a language like Python instead
of shell.

The other examples would benefit from tests too.  Probably best
to settle on a framework to write them in, then add more tests.
