boolean-related tweaks of mine); also stop wrapping the bad_chr
parameter of parse_mbchar() in #ifdefs for cleanliness, as the
allow_tabcomp parameter of check_operating_dir() isn't wrapped in
#ifdefs, and don't set bad_chr to TRUE when we get a null byte in a
multibyte string, as it's not an invalid multibyte character

prone to off-by-one errors that lead to memory corruption and I can't

two-column characters at the beginnings and ends of long lines (i.e,
lines with $'s added), as the problems don't occur with ncurses 5.4, and
