>Description:

	The following command fails:

# expr '>' : '.*'
expr: syntax error

	It should return 1 (the length of the string '>') instead.
	Note that Linux's expr does right thing.

>How-To-Repeat:

	See above.

>Fix:

	Unknown. It seems our expr threats '>' and operator
	and not as operand for ':' operator.
