+ + modify tset -w (and tput reset) to update the program's copy of the
+ screensize if it was already set in the system, to improve tabstop
+ setting which relies upon knowing the actual screensize.
+ + add functionality of tset -w to tput, like the "-c" feature this is
+ not optional in tput.
+ + add "clear" as a possible link/alias to tput.
+ + improve tput's check for being called as "init" or "reset" to allow
+ for transformed names.
+ + split-out the "clear" function from progs/clear.c, share with
+ tput to get the same behavior, e.g., the E3 extension.
