 Some people like to have logAllRefUpdates even for bare repositories, and if
 shared, git-gc breaks them.

Why is it sane to do this unconditionally, instead of putting in another
else or something?

  Huh indeed, the proper patch should have been:

-		}
+		} else {
+			adjust_shared_perm(log_file);
+		}

  It was inattention on my end, I focused more on writing a test case
than on the one liner fix. Sorry.

Because adjust_shared_perm() checks for shared_repository, and returns 
when there is nothing to do.

IMO this is a sane convention, since you _never_ want to do this 
unconditionally anyway, and you avoid a lot of identical "if () adjust()" 
constructs.

Ooops.  I think I missed your point, namely that this should only be done 
when no error occurred.  I just blame it on the short snippet.

Sorry,
