   Where are you seeing this situation handled improperly?

   I do know of one case where,  if I Ctrl-C out of an ncurses program, 
 the terminal isn't completely reset.  In xfce4-terminal,  if my 
program has turned mouse movement events on using CSI ?1003h [0],  and I 
Ctrl-C out,  then moving the mouse over the terminal generates garbage. 
In that case,  it's to be expected;  I'm the one who sent the control 
code,  not ncurses.  ncurses does (in my experience) a complete job of 
cleaning up anything it's reset.

   Seems to me that if you're encountering cases where ncurses is not 
resetting the screen correctly after Ctrl-C,  then perhaps that ought to 
be fixed,  rather than relying on reset/clear/etc.

   This is the usual instance where I find myself applying reset/clear. 
 The programs involved are my own,  which sadly means I must claim the 
bugs as my own as well.
