PATCH: _rlogin splits up into three functions (still one file)

["Bart Schaefer" <schaefer@xxxxxxxxxxxxxxxxxxxxxxx>]

For consideration (i.e., not yet committed).  This makes it a little easier
to write a wrapper, e.g. Jay's Kerberized version could become

	#compdef krlogin krsh krcp
	compdef ${words[1]:t:s/k/_/} ${words[1]:t}
	_rlogin "$@"

Though of course that needs to become documented before he can rely on it.
