Hi Bram,
By default, 'm' is not contained in 'formatoptions', so automatic wrapping not
work when multi-byte characters are continuously input.
Of course, I should set it up with my .vimrc, but I saw some people in trouble
with this case.
I am very happy if you can include an attached patch.
I think this change does not affect non-multi-byte-inputting people.
