For user it only matters when/if one wants to attach to the dtach'd
terminal (i.e. rarely). Then if the terminal chosen is knows subset of
the control sequences any of the terminals users might use then it is not
much of a problem -- the terminal just doesn't work optimally, display
colors or something.

In your tests you could just run `TERM=xterm make test` (and forget the
