python -U breaks import with 2.1


Anyone understand -U?  Like, should it work, why is it there if it doesn't
and isn't expected to, and are there docs for it beyond the "python -h"
blurb?

Last mention of it I found in c.l.py was

Well, with -U on, Python will compile "" into u"",

last I tried, Python didn't even start up :-(

An earlier msg (08 Sep 2000) said:

"""
Note that many thing fail when Python is started with -U... that
switch was introduced to be able to get an idea of which parts of
the standard fail to work in a mixed string/Unicode environment.
"""

If this is just an internal development switch, python -h probably shouldn't
advertise it.
