Re: [PATCH 05/15] refs.c: update rename_ref to use a transaction

Change refs.c to use a single transaction to copy/rename both the refs and
its reflog. Since we are no longer using rename() to move the reflog file
we no longer need to disallow rename_ref for refs with a symlink for its
reflog so we can remove that test from the testsuite.

Do you mean that we used to do a single rename(2) to move the entire
logfile, but now you copy potentially thousands of reflog entries
one by one?

Hmmmm,... is that an improvement?
