For the record, should we want to remove the option of having a (possible second) minus sign after the radix specification, the expression

should be removed from NumberParser>>#nextNumber and #nextInteger
But I haven't tested this.
Some unit tests might fail since this 'feature' seems to be supported explicitly.
