	* ftpcmd.y: Fix up grammar so that single character token names
	are no longer used; this was breaking the build using bison on
	HP/UX because some system headers declare structures with members
	having all-uppercase field names and bison puts the token name
	#define statements in front of the C declarations section in the
	output, causing them to be in force while those headers get
	#included.  There doesn't seem to be much purpose in not just
	using character constants, anyway.
