Weird.  What the heck is 0xa0 doing in string.whitespace?  Oh, waitasec,
0xa0 is non-breaking-space in ISO-8859-1.  But no, string.whitespace is
hardcoded to the US-ASCII whitespace chars, all of which are in
range(128) -- your locale shouldn't matter.

Just, can you run the following commands and tell me what you get:

  python -c "import string; print [hex(ord(c)) for c in string.whitespace]"
  python -S -c "import string; print [hex(ord(c)) for c in string.whitespace]"
  LANG=C python -c "import string; print [hex(ord(c)) for c in string.whitespace]"
  LANG=C python -S -c "import string; print [hex(ord(c)) for c in string.whitespace]"

(On my Linux box where LANG=en_CA normally, I always get the six
US-ASCII whitespace chars.)
