If the user has asked that a new value be set for a reference, we use
check_refname_format() to verify that the reference name satisfies all
of the rules. But in other cases, at least check that refname_is_safe().

It isn't clear to me what "in other cases" exactly refers to.  A
request to delete a ref would obviously one of those that do not
"ask that a new value be set", but are there other cases?

The other case is `verify`, which can be used to check the old value of
a reference without modifying it. `verify` is exposed via `git
update-ref --stdin`

Thanks.
