PATCH: Capitalize a parameter containing combined characters

["Jun T." <takimoto-j@xxxxxxxxxxxxxxxxx>]

I did some quick tests of parameter expansion with combined characters,
and found a small bug:

zsh$ x=éfg            # é is a combined character, e + U+0301
zsh$ echo ${(C)x}     # capitalize
ÉFg                   # should be "Éfg"

This may be fixed, for example, by the patch below.
