Curiosity is the very basis of education and if you tell me that 
curiosity killed the cat, I say only that the cat died nobly.

>Description:
A currently-broken-for-me mercurial self test uses tic like this:

> mkdir "$TESTTMP/terminfo"
> TERMINFO="$TESTTMP/terminfo" tic "$TESTDIR/hgterm.ti"
> TERM=hgterm TERMINFO="$TESTTMP/terminfo" hg status --config color.mode=terminfo --color=always -A

roy told me that currently only this version is supported:

> mkdir "$TESTTMP/terminfo"
> cp "$TESTDIR/hgterm.ti" "$TESTTMP/terminfo"
> tic "$TESTTMP/terminfo/hgterm.ti"
> TERM=hgterm TERMINFO="$TESTTMP/terminfo/hgterm.ti" hg status --config color.mode=terminfo --color=always -A

It'd be nice to be more compatible with ncurses and support the former version
as well.

(Neither the self test nor the curses code seems to have changed
since the test last worked, so I'm not sure if this change would
fix it.)

See above.
