NN screws up screen if terminfo entry has flash capability

[Pim Zandbergen]

We run NN on an AT&T 3B2/600 (SysVr3.1.1), all terminals here are
Wyse 50's.

When I first ran NN, it  failed to clear the screen before it drew 
the next one. In stead of the clear-screen escape sequence
">\EA00" was sent to the screen.

This looked a lot like the flash capability I added to the
Wyse-50 terminfo entry (flash=\EA04$<200>\EA00). After removing
this capability, everything worked fine.

I haven't yet really dug into the sources, but it looks like the
flash string is sent to the screen literally, instead of using
the flash() function in curses(3X).

Does anyone have a patch for this, so I can make my Wyse-50
flash again when I make a mistake in vi? :-)
