Comment (by teor):

 Here's how to do an equality check right:
 (Every check must be a range check, not an equality check.)

 I think all the current tor code is ok, but it's easy to mess up these
 comparisons.

 We should add a comment to tor_version_compare() recommending using
 !tor_version_as_new_as(next version) or tor_version_same_series(), to
 avoid the git tag issue.
