I'm enclosing my current terminfo description for the vt100.
I notice two significant problems with the one previously posted.
(1) Your method of dealing with graphics characters is different
from what AT&T is going with, (2) you put the status line on the
bottom rather than on the top.  (Most people, given a choice, prefer
it on the top, also it doesn't get clobbered when you clear the screen.)
I have no quarrel with your observations about automatic margins, but
neither method seems to handle the vt100 right (outputting a char in
col 80 sets a flag in the terminal, outputting a char elsewhere seems to
be the only way to clear that flag.)

Explanation of graphics characters.  The vt100 is the definition, but only
for those chars that are line drawing in nature.  The acsc (alternate char
set chars) lists pairs of chars, for aAbBcC, to get standard a you output A,
to get b output B, etc.  enacs must be output before sending anything out
in the acs (once) to get the terminal in the mode.  smacs/rmacs turn on
and off the alternate char set (the one with graphics in it.)
