[PATCH] copy-prev-shell-word broken since 4.3.11

[Carl Drougge <zsh@z42.net>]

I used to be able to use copy-prev-shell-word to copy the word to the left of
my cursor. At some point this broke, always giving the last word on the line,
and I couldn't be bothered to look into it. Now I have looked at it. It works
in 4.3.10, not in 4.3.11.

I have never looked at the zsh source before, but hopefully this patch doesn't
break something else. The bufferwords function (and the whole lexer) seems
pretty, uh, frightening.
