Ooooppsss...  My mistake.  It was the V6 password encryption that did the
folding to a more limited character set.  It's been a long time since I
last read the "password security" paper, and I had gotten the two mixed
up.  The V7 algorithm does not do this.  One wonders why; it seemed a
useful precaution against cryptanalytic (as opposed to brute-force-search)
attacks on passwords.

My thanks to Steve Bellovin for pointing this out.
