Why multibyte for original-article buffer

[Stefan Monnier]

I've been running with the following patch with good results.
Also the patch makes sense to me: the original article is a sequence of
bytes (i.e. encoded chars), so a unibyte buffer makes a lot of sense
(it's more efficient and is likely to hide fewer bugs).

Yet the code currently explicitly sets the buffer to multibyte mode.
Does anybody know why?
