V10/ncurses/screen/README.delwin

Symtoms:

Programs that use curses can grow when windows are added (addwin) but
not free up all the space when the windows are deleted (delwin).

Cause:

Looking at the code, addwin() allocates some space. If the allocation
fails, it frees up some data structures. The delwin() function does
something similar but does not do a complete job. The additional lines
have been added.

Installation:

This file should be installed in /usr/src/lib/libcurses/screen/delwin.c .
After that, the curses library needs to be remade, then all affected
application programs need to be recompiled.
