Indeed.  I suggested long ago to retrofit the MSDOS code into a Posix
text terminal.  This should be almost trivial: all we need is to
replace direct screen writes with terminfo commands and stdio output.
All the rest can be kept almost verbatim.  The relevant functions are
XMenuCreate, XMenuAddPane, XMenuAddSelection, XMenuLocate,
XMenuActivate, and XMenuDestroy (and their few subroutines), all found
on src/msdos.c.  Of these, XMenuActivate is the only one that is
complicated; all the rest are really trivial.
