That shouldn't cause problems in termcap, though, because this is one
of the supported tgoto() parameter modes.  One does have to omit an
explicit "ho" capability if that's the only way to achieve it, but
any termcap-using software ought to be smart enough to use "cm" to
accomplish an "ho" effect when the former is given but not the latter.
