My thinking here was that if you're using -T, you're not looking to
update terminal modes but just querying the terminfo database (after all
the first line of the manpage reads "initialize a terminal or query
terminfo database"). I'm ok with a new option too, but on the off chance
that there's any other software that expects to be able to query the
database without a tty, it'll have to be modified to use this new option
for ncurses tput too.

Interesting. I'm not sure what's the correct approach here.
