There's been previous threads about this.  Unsigned shift right seems
to be quite useful for some cryptographic functions.

I found when rewriting crypt() in Python that nearly all the right
shifts were by constants, so I could write something like

    ((t >> 18) & 0x3fff)

to trim off the sign bits.
