Hmph, then the advice message would suggest "update-ref"?

Ah, no.  Because the message may be reused to create a tag with
different tagname, which is very likely because one reason for the
refusal to update the ref could be that the name was already taken,
and that would create a mismatch between tagname and refname.

OK, so ...

... this is a reasonable thing to have in a more user-friendly
feature, like your -c above.

Yeah, I am OK with "leaving TAG_EDITMSG behind" and a future "tag
-c/-C $another" to coexist.
