I see.  Learn something new everyday.

I use `display-graphic-p' in many places to guard some code
that might try to use graphic-display capabilities.

Apparently some of those uses might not really be appropriate
(might not do what I was expecting).  Thanks for the info.

No, that would be pretty useless.  It wouldn't even make sense
to test it in a Dired mode hook (readin or whatever), as the same
Dired buffer could be shown either or both of the two types of
frame.

I'll just remove the `display-graphic-p' test and leave only
the user option as the test.
