(This bug report unfortunately got no response at the time.)

The command in question now produces an 11-char short hash, which I
think is pretty rarely ambiguous, in my experience, so I don't think
there's anything more to fix here, and I'm closing this bug report.

If there's still a problem here, please respond to the debbugs address
and we'll reopen.
