SHAs aren't ordered like SVN revisions are (so given two arbitrary
SHAs and nothing else I can't determine which came first) but they do
still have an ordering in the repository.

Regardless, we can say: fixed in commit SHA. They can pull, and if
"git show SHA" shows the revision then they've got it. Otherwise they
don't.
