[PATCH 3/3] Don't flush the prompt when resizing the terminal within TUI

[Patrick Palka <patrick@parcs.ath.cx>]

This patch removes the ancient code that is responsible for forcing the
prompt to get flushed and executed when tui_getc() detects that the
terminal has been resized.  This behavior is unintuitive and seemingly
unnecessary.  I tried figuring out why tui_getc() behaves this way, but
git-blame does not reveal anything informative about this code.  It
probably has something to do with avoiding to print KEY_RESIZE keys, but
the previous patch prevents that from happening anymore.

gdb/ChangeLog:

	* tui/tui-io.c (tui_handle_resize_during_io): Remove parameter.
	Change return type to void.  Don't call dont_repeat.
	(tui_getc): Adjust.
