[INET]: Justification for local port range robustness.
There is a justifying patch for Stephen's patches. Stephen's patches
disallows using a port range of one single port and brakes the meaning
of the 'remaining' variable, in some places it has different meaning.
My patch gives back the sense of 'remaining' variable. It should mean
how many ports are remaining and nothing else. Also my patch allows
using a single port.
I sure we must be able to use mentioned port range, this does not
restricted by documentation and does not brake current behavior.
