Automatically link git commit hashes in commit messages

Would it be possible to link to git commits if the hash is included in a commit message? For example, when a commit is reverted using git revert, the default commit message created by git includes:

This reverts commit 320e76b6d416de1aebb0276e170fe31cfdb6400b.

It would be nice if the Fisheye interface linked this hash to the previous commit. It should be fairly easy to detect commit hashes as a hexidecimal string of a certain length (even if only full-length hashes are detected, although it would be nice if truncated ones were linked too).

Another possible use case is where one commit relates to a previous commit - the new commit can include the hash of the related commit in its commit message.
