  Implement comment commits

  This ended up requiring a little refactoring here and there, as well as a fix
  for typeobj after running into a bug. Also made the commit message unmarshaling
  a bit more durable, after running into a case where the error message that gets
  produced for an invalid commit is not very helpful.

  Currently comment commits are not very well tested. The tests for commit objects
  in general need to be rethought completely, so they better test the hashes as
  well as message head parsing.
