/*
 *	Name:		save_cmdfile()
 *
 *	Description:	Create a 'cmdfile' for the format command from
 *		the information in 'disk_p'.  The layout of a 'cmdfile'
 *		file is as follows if the label source is not DKL_EXISTING:
 *
 *			partition
 *			a <start_cyl> <n_blocks>
 *			...
 *			h <start_cyl> <n_blocks>
 *			quit
 *			label
 *			quit
 *
 *		If the label source is DKL_EXISTING, then no file is created.
 *
 *		Returns 1 if the file was saved successfully, and -1 if
 *		there was an error.
