It can't, at least not like this, simply because if the server gets, e.g.:

HASH somepath 10 20

.. it can mean any of the following and it's impossible to tell which one:

a) pathname = "somepath", start-point = 10, end-point = 20
b) pathname = "somepath 10", start-point = 20
c) pathname = "somepath 10 20"

It would work with reversed order, with mandatory start and end 
points before pathname, but if RANG catches up (and it should, 
because it has big potential), wouldn't it be a little weird to have 
separate way for using ranges with HASH?
