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

[Patrick Palka <patrick at parcs dot ath dot 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.

Removing this dubious code does not seem to cause any regressions in
TUI.  TUI handles resizes and user input just fine still.

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.
