test-check-commit-hg.t: automatically test all 'draft() and ::.' changesets
We introduce a test-check-commit-hg.t file that will happily run the
check-commit file on all draft changeset under the working directory.
This should help newcomers to catch up with the rules. (And will helps old timer
from time to time).
