	Arguably it will, due to the use of tabs as the

	I like the idea, but not the implementation.

	1) I'd suggest slashes, and require they be the first
	and last characters of the string, like
		valid users = /tom/jerry/tim smith/
	2) during a cut-over period fom 2.2.0 to 2.3.0, strings 
	   without slashes should be interpreted as before, and
	   a warning message issued at log level 0
	3) after the cut-over period, the slashes should be 
	   required, and the erronious line rejected.

	This makes the option unambiguous, "except for a short
	and bounded period" (the latter quote is from a safety-
	critical-systems course I took some years back (;-))

	There is already code to parse slash-lists, so using it
	would be a smallish change too.
