Nice illustration to convince anybody that "git describe --tags
--contains" should give "past present future" (or "past^0 present
future^0").  I am not sure if it is a good idea in general to change
the output to include "present" when "--tags" is not given, though.

For _this_ example, it does give us a more useful result, but the
example was to constructed to illustrate the case where the new
behaviour is more useful, and does not serve to convince us that it
won't have negative impact X-<.
