intl patches (25)

[Bruno Haible]

A slightly stricter check for the 'nplurals' value. The current code, based
on strtoul, accepts numbers starting with a minus sign. Here is a patch to
reject them.

	* intl/plural-exp.c (EXTRACT_PLURAL_EXPRESSION): Reject numbers that
	don't start with a digit; nplurals must be positive.
