DEL is a control character that should be (essentially) ignored when written to
a screen.

This was the case for xterm until 2002 Dec 8 when T. Dickey changed the XFree86
version.  This was a mistake, as evidenced by the fact that he has changed it
back (at my prompting) recently (since the fork).

The correct fix is to change the initialization of VTPrsTbl.c's ansi_table[0x7f]
from CASE_PRINT to CASE_IGNORE.  All the other tables defined in this file seem
to have CASE_IGNORE for DEL.

This change was independently derived by me.
