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.

Otherwise, returns \l Invalid.
If the valid range consists of just positive integers (e.g., 32 to 100)

evaluated as \l Intermediate, as otherwise the user wouldn't be able to
