	OK This is not quite the answer that you seek, but it may help.

	Whenever I want a script to read into a variable (say 'fubar')
	then I use:

		read fubar junk

	This will capture any 'extras' into 'junk', which I ignore.

	Of course it doesn't work unless there is whitespace after
	legitimate input, but it can be extended for any number
	of inputs on a line:

		read x y z junk

	etc.
