* cmd.c: Added single_dirsize_cmd(), which computes the size of

the currently selected panel entry and moves down. Suggested by
	ForestCreature on mc-devel.
	* cmd.h: Likewise.
	* main.c (midnight_callback): When the space key is pressed and
	the command line is empty, single_dirsize_cmd() is called.
