Comment (by teor):

 Thanks!
 This looks almost ready to go.

 But please make:
 {{{
 tor_version_parse("Tor 0.3.0.0-alpha-dev", &bad)
 }}}
 a separate statement with an appropriate comment. It's confusing to put it
 with the other check. Also, if "Tor 0.3.0.0-alpha-dev" fails to parse,
 that's a coding bug. So you could do something like:
 {{{
 /* We should always be able to parse this version string */
 if (BUG(tor_version_parse("Tor 0.3.0.0-alpha-dev", &bad) == -1)) {
   return 0;
 }
 }}}

 Nitpick:

 I was confused what `cur` and `bad` meant. We could use longer names for
 them. I'd like to try to make it clearer that `cur` is the parsed form of
 `platform`; and that `bad` isn't the only bad version, and it is the
 parsed form of "Tor 0.3.0.0-alpha-dev".
