Mac OS X 10.4.x uses ncurses, even with the curses API.

We could say the same thing for the current Debian/stable.
Now I just hope that Mac OS X 10.5 will use ncurses 5.5.

According to ldd, less uses libncurses (not libtermcap).
The less man page says:
Less uses termcap (or terminfo on some systems) [...]
/usr/share/doc/less/README.Debian doesn't say anything.

Changing the terminfo database (e.g. with infocmp to retrieve some
data + tic to install them, possibly modified, in my $HOME directory)
changed the behavior.
