* At first glance it seems like we shouldn't care if the terminal type
* is changed inside visual mode, as long as we assume the screen is
* a mess and redraw it. However, it's a much harder problem than that.
* If you happen to change from 1 crt to another that both have the same
* size screen, it's OK. But if the screen size if different, the stuff
* that gets initialized in vop() will be wrong. This could be overcome
* by redoing the initialization, e.g. making the first 90% of vop into
* a subroutine. However, the most useful case is where you forgot to do
* a setenv before you went into the editor and it thinks you're on a dumb
* terminal. Ex treats this like hardcopy and goes into HARDOPEN mode.
* This loses because the first part of vop calls oop in this case.
* The problem is so hard I gave up. I'm not saying it can't be done,
* but I am saying it probably isn't worth the effort.
