That's not necessarily a Good Thing.

You might consider making a special case on initialization to detect if it's
got TERM=screen{whatever} and/or smso containing SGR 3.

screen equates SGR 3 to standout, has done this for more than twenty years,
and doesn't support italics (unless someone's going to modify screen).

On the other hand, ncurses can support italics - not a lot of feedback on that 
though.

An application that sends SGR 3 (hardcoded ECMA-48 italics for instance) will 
get standout.
Likewise, an application using screen's terminal description will send SGR 3 
for standout.
So you can only do this reliably for applications using the terminal 
description.
