In order not to be dependent on `tput` being available, I've found that the
following that @MarkPlotnick (from unix.stackexchange.com) inferred works just
as well. Just replace the function `ShowTerm()` above with:
function! ShowTerm()
silent !read -sN 1
redraw!
endfunction
This depends on `bash` being used as the shell (or others that have a similar
read call).
