Yup, I only took a brief glance at the patch, and I didn't quite see
the point of duplicationg an almost parallel mechanism to an
existing (--single-branch, set-branch) pair of the feature, only to
replace "branch" with "tag" (the patch noise / code churn did not
seem worth it).

In other words, is there a situation where a branch cannot be used
(or using a branch is more cumbersome or awkward) when the user
wants to use a tag with this patch?  As users can just as easily
move tags as they can move branches, the verb "freeze" used in the
proposed log message probably does not reflect reality anyway, as
you already pointed out.

Thanks.
