* commands/help.c: Include `grub/mm.h' and `grub/normal.h'.
	(grub_cmd_help): Print the cmd->name before the cmd->summary. Cut the
	string using string width.

	grub_print_spaces and not print_spaces.
	(print_timeout): Likewise.
	(print_spaces): Move to...
	* include/grub/term.h: ... here. Change the name to grub_print_spaces.
