Yeah, it's not very useful in special mode buffers, is it?  On the other
hand, it's pretty useless in all modes that aren't text-like, whether
they're read-only or not, so I'd expect people to only switch the mode
on in modes that inherit from text-mode, probably.

I'm not sure anything can be done for
global-display-fill-column-indicator-mode, though -- a global mode is,
well, global?  Is there any mechanism in place for making global modes
less global?
