My opinion: I think globbing should be supported for tty name matching
in the tty_log{in,out} file, or whatever it ends up getting called.  I
see it as fundamentally different from /etc/ttys because /etc/ttys is
not just a lookup table but also the driving list for the getty
spawner (init, currently, but conceptually separate).  Supporting globs
in /etc/ttys would mean that the getty spawner would have to expand the
globs without anything to expand them relative to.  (Except perhaps the
contents of /dev, but I don't like that because losing an entry in /dev
becomes a silent failure mode instead of the present noisy one.)

If we separate the list-of-ttys for the getty spawner from the table
that describes those ttys, I would say the latter _should_ support

And I think the file under discussion here should support globs, since
it is entirely a lookup table.

One could argue that "globs" should really be "regexps", but I see no
need for that much generality.
