There is more going on. ncurses also automatically sends 
the relevant string automatically, in _nc_mvcur_init() (called via 
newterm() from initscr(), in the ncurses source code).

I wonder what the purpose is of do_enter_ca_mode now. Maybe it is just a 
left-over, necessary for other (non-ncurses) curses libraries, or xterms 
with broken terminfo's.

Yes, there are variations for various other operating systems/environments 
there.
