On some systems (eg on my AT 386 with ISC's 386/ix) I have observed
a problem when using 'showmode': As far as I've tracked it down,
it seems to occur, if a ':map!'ped key-sequence leaves INSERT
mode, then scrolls the screen up and finally enters INSERT-mode
again. In that case, 'vi' forgets, to delete the mode-line and
scrolls it up on the screen together with the text. An unexperienced
user would think, that the mode-line has entered the edited text,
but CTRL-L shows, that this has not happened.

Now my question: Is this a problem with the "terminfo"-entry or
a bug of 'vi' (maybe it was not noticed, because all the gurus
including those who have the source for 'vi', tend *not* to use
'showmode' :-))
