wcwidth.c update

This is to let you know that I just fixed a minor bug in

  http://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c

Please update, in case you use this routine in your software.

Details:

Even though the comments still listed the rule

 *    - Hangul Jamo medial vowels and final consonants (U+1160-U+11FF)
 *      have a column width of 0.

the support for this rule got a ccidentally dropped when I regenerated
the tables 2002-03-28 for the Unicode 3.2 update. This is now fixed.

Thanks to Jungshik Shin for bringing this to my attention.
