unicodedata.east_asian_width().  You can still implement your own
simple width() function using it like this:
    def width(u):
        w = 0
        for c in unicodedata.normalize('NFC', u):
            cwidth = unicodedata.east_asian_width(c)
            if cwidth in ('W', 'F'): w += 2
            else: w += 1
        return w

iswide() for east asian width manipulation. (Inspired by David

no padding is added for UCS-4 builds. (Suggested by Martin v. Loewis)

ranges) -- but thanks to the 2.0 compression scheme, this doesn't add
a single byte to the resulting binaries (!)

Closes bug #117524

- fixed attributions
- moved decomposition data to a separate table, in preparation
  for step 3 (which won't happen before 2.0 final, promise!)
- use relative paths in the generator script

I have a lot more stuff in the works for 2.1, but let's leave
that for another day...

- use unidb compression for the unicodedata module.  on Windows,
  the new unidatabase module is 120k, down from nearly 600k.
