Well, I should be able to configure my applications locally here to be
able to speak to such a terminal.

Here's the deal with termcaps and terminfos:

in Debian, the termcap information is found in the termcap-compat
package, which includes the termcap file - basically a monolithic file
full of termcap entries. Nothing in debian depends on termcap - they all
use terminfo.

in Debian, a few of the basic terminfo entries are found in
ncurses-base, and the rest (including scoansi) are found in ncurses-term

When I first tested this patch, I didn't have ncurses-term installed.
Now that I installed ncurses-term, things still don't look right, but
they didn't look right in this terminal after I ran
$ export TERM=xterm
either, so I assume it's trying to emulate scoansi now rather than
xterm. But this is the YMMV part of the experiment. Let us know how it
goes.

This is a patch file generated from manual changes I made directly to
debian sid's current gnome-terminal sources.
