I think it is a great way to avoid all sorts of stupid bugs
when char is inadvertently sign-extended.
I try to write code such that it will work with signed char,
but at the same time -funsigned-char gives additional protection -
even if some code is potentially buggy wrt signed char, it
will actually work.
(vi was particularly bad in that regard)
