curses/termcap vs. autowrap on DEC terminals

[Brandon S. Allbery]

As quoted from <853 at per2.UUCP> by dag at per2.UUCP (Daniel A. Glasser):
+---------------
| Many "VT100" clones/emulators do not mimmick the DEC terminal behavior
| properly.  Some do.  The best bet when you find programs screwing up
| the screen display through curses is to make sure the tab settings
| on the terminal are the default 8 column tabs (9 17 25 ...), that
| the TERMCAP entry for the terminal has auto margins false and that the
| terminal itself has autowrap turned off (this should actually not
| be required).
+---------------

Alternatively, set the ":xn:" attribute in the termcap and leave auto-wrap
on.  ("xn" means that a linefeed from column 0 doesn't always get acted upon;
this basically avoids the problem, since curses thinks it's in column 0 when
the VT[12]xx thinks it's in column 80+.)

I use this on many systems with no problems.
