FYI, this operation is also valid in GNU Screen, so suggest adding a
strncmp for that as well.  Like xterm, it can be e.g. screen-256colors
&c as well as just screen, so only compare the leading 6 chars.

I'm not actually using this feature, because e.g.
    mpg123 --title http://radio1.internode.on.net:8000/10
sets the title to "10" instead of anything useful (e.g. ICY-NAME or
ICY-META StreamTitle).
