Why is is desirable to set specifically TERM=xterm instead of, say,
vt220, or whichever vt entry describes wscons the closest?

For multi-line scroll the patch just calls scrollup/scrolldown, but
that's not what the single-line scroll commands do (see
wsemul_vt100.c)

I'm actually not entirely convinced that it's even correct to describe
vt220 as having sf/ind scrolling capabilities, b/c the vt220 scrolling
sequences take the scrolling region into account and the terminfo
capabilities for scrolling are defined to operate on the whole screen
as far as I can tell.

So in its current form I don't think this patch is suitable and I'm
not convinced it's needed at all.
