These look all sensible. Especially thanks for reordering the code
to feed the real refname for the new branch in the "checkout"
codepath.

"--no-create-reflog" should override the configuration set to "true"
or "always". Also "--create-reflog" should override the
configuration set to "false".
If the problem was inherited from the original code before your
change (e.g. you set logAllRefUpdates to true and then did
"update-ref --no-create-reflog refs/heads/foo". Does the code
before your change ignore the command lne option and create a reflog
for the branch?), then it would be ideal to fix the bug before this
series as a preparatory fix. If the problem was introduced by this
patch set, then we would need a fix not to introduce it ;-)

Here you need to have another free(), as this block makes an early
return and you end up leaking refname.

This change is to make sure that 'true' does not affect tags (but
'always' does as seen in the later new test)? I am just double
checking, not objecting.
Thanks.
