Doc fix in QIntValidator::validate() and comment on a test

Browse Source 
The doc said positive values for a negative range were intermediate
but the code actually rejects them if the value has an overt plus
sign, so make clear that intermediate is only for the case without a
sign. Incidentally comment on a test where it might not have been
obvious to the reader that a space is the locale's digit-grouping
chracter.

If the valid range consists of just positive integers (e.g., 32 to 100)
