cjkwrap.fill not working unless keyword argument break_long_words is True

[kkew3]

For example,

print(cjkwrap.fill(u"最終的に良いラッピング", 10, break_long_words=False))

gives

最終的に良いラッピング

Since CJK characters can be broken at every character boundary, break_long_words=False shouldn't, as far as I'm concerned, prevent wrapping from happening.

Thank you so much!
