remove DB's hacks to work around problems with ncurses' display of

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
there's no easy way to fix the same type of problem with doing a regex
replace of "^" on a line beginning with a two-column character
