Subject: [PATCH] (_rl_move_vert) [__GO32__]: fflush the stream, to make sure
 cursor position is up-to-date. (space_to_eol) [__GO32__]: Clear the screen
 and home the cursor. (insert_some_chars) [__GO32__]: Don't write directly to
 the screen in DJGPP versions 2.x (it doesn't work). (delete_chars)
 [__GO32__]: Ditto.
