Subject: show-branch: Be nicer when running in a corrupt repository.
X-Git-Tag: v0.99.7a~4
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=0a2ba73860211efec479396c33ba381056715be5;p=git.git

show-branch: Be nicer when running in a corrupt repository.

We may end up trying to print a commit we do not actually have but we
know about its existence only because another commit we do have refers
to it.
