This would be needed in any case because "explicit-name" should never
get assigned to by `modify-frame-parameters'.  I'm not entirely sure
though whether every possible setting of "name" gets correctly reflected
in "explicit-name", but such a bug would have existed before.  At least
I'm tempted to move the

  f->explicit_name = ! NILP (name);

in set_term_frame_name as

  f->explicit_name = Qt;

to the end of the else branch below to catch the cases where there's no
change either because the strings are equal or there's a name clash, but
that's probably only a minor issue.

I wouldn't care if anyone came up with a completely different solution ;-)
