I'd be fine with that.  I'd also be fine with keep the bar there all
the time.  But it seems like the optimal solution would be for the bar
to appear and disappear, but not change the divider location.  Is that
possible with `racket/gui'?  That would make it more reasonable to
show more of the error when it's more than 1 line, as well.
