 I was thinking about removing the leading 0 from our version numbers, and
 realized that we can't[*] do that yet: tor_version_parse assumes that if
 you have a three-number version, you may not have a tag.

 Let's allow two-number versions and three-number versions to have tags.
 And let's look into other ways to fix tor_version_parse.

 [*] There are other ways to remove our leading 0.  We could use four-
 number for alphas, and three-number versions for stable versions, as in
 "2.7.0.1-alpha, 2.7.0.2-alpha, 2.7.0.3-alpha, 2.7.0.4-rc,  2.7.5".  Or we
 could have Tor report its vesion as 2.7.1-alpha to the UI, but advertise
 it as 0.2.7.1-alpha to other tors to work around this bug.
