[PATCH] readline warning fixes

[Elias Athanasopoulos <eathan@otenet.gr>]

Hello!

Some warning fixes to readline. BTW, shouldn't comments end in a 
period followed by two spaces?

Regards,
Elias

readline/ChangeLog

2002-12-14  Elias Athanasopoulos  <eathan@otenet.gr>

	* histexpand.c (get_history_event): Cast const char * to char *
	to avoid compiler warnings.
	* display.c (_rl_move_cursor_relative): Likewise.
