backout VIS_HEX. guenther@ points out that the C89 \xff encoding

idiotically accepts more then two hex digits following the \x, even
on platforms where a char has 8 bits. It is therefore dangerous to have
an almost-bit-not-quite compatible format in vis(3).

The VIS_ALL (encode all characters) option introduced in the same commit
remains.
