That may be due to my changes making cvvis work for Linux, and
unfortunately, your changes undo that.

I suppose you set your non-blinking cursor with something like
echo '\e[?16;0;112c'. Unfortunately, I also have to use an
\E[?...c sequence for cvvis (and, accordingly, another one to reset
it in cnorm which is probably called at the end of vim etc.). I
don't see a way to do the one (setting the cursor size) without the
other (affecting whether "soft cursor" is used) -- at least not from
what I see in /usr/src/linux/Documentation/VGA-softcursor.txt (don't
know about other ways).

So maybe this interface is not optimal and should be changed -- it's
rather new, so that might be possible if one asks the authors listed
in that file...

BTW, your terminfo entry otherwise differs quite a bit from the
current one in terminfo.src. Did you do the modification against an
older version?
