Right. If w < 0, bad things happen in the code just following. If
w can indeed be negative there, maybe that code block should be simply
skipped.
any problems, in C or en_GB.utf8 locale, but it seems quite possible to
me that the wcwidth() of a `mbtowc() < 0' could be -1, as above?
wcwidth() should be negative only if wide_char is non-printable.
The code checks if iswcntrl() or iswspace(), and if so, skips the
assert and output. If it is a wide control character, then it's not
printable, right?
