Supposedly, it's still supposed to be close to release (or freeze,
anyway) time, so a temporary solution is still needed.  :)

I think the idea was that apps would build against whatever -dev package
was installed; this is incomplete without handling #define UTF8
automatically.  It's not going to be reasonably transparent without more
work, so for the time being I'd agree--make it a completely different

I just spent some time bashing on it, trying to fix line drawing characters,
and I'm bleeding out the ears--slang is not an easy library to edit.
(Perhaps the person who wrote this patch originally could step forward
and try to finish it.)

(Basically, it seems that slang uses the high bit of the color to mark
characters as ACS; but the color is 0xFF000000 in the UTF8 version, not
0xFF00, and changing this means changing a bunch of shifts in odd
places.  Maybe it's easier than it seems; I don't know enough about this
codebase to fix it in a reasonable amount of time.)
