It means that what Screen uses for standout mode, ANSI (and rxvt) uses
for italics mode. I don't know why this is the case, but the fact that
it is means that making screen support italics would be a PITA.

If we make screen use \033[3m for italics (instead of its current use
for standout), and \033[7m for standout (ANSI's "negative image"), then
all pre-existing termcap/terminfo definitions for screen will be wrong,
and users will have to be especially careful not to use newer versions
of screen with older termcap/terminfo definitions for screen.

Nevertheless, it seems like it might not be a terrible idea to start
migration, or at least support a configuration option for it. I don't
know when such a change might be effected, though.
