Subject: [PATCH 5/8] refs: use is_pseudoref_syntax() in refname_is_safe()

From: Jeff King <[email-masked]>
Date: Mon, 29 Apr 2024 04:23:20 -0400

The open-coded logic in refname_is_safe() predates the addition of
is_pseudoref_syntax(). But now that we have it, we can make use of it.
This shortens the code, but also makes sure we use a consistent
definition of a pseudoref.

Note that refname_is_safe() allows HEAD, which of course is not itself a
pseudoref by the strict definition (since it can be a symref). But the
syntax for the two is the same, and that is all that we care about here.
