Strikethrough

[ghost]

printf "\e[9mstrikethrough\e[0m\n" works in st doesn't in dvtm

Strikethrough text is not currently supported by ncurses attributes

available attributes as per /usr/include/curses.h:1094 (ncurses 6.1)

Thus this is an upstream issue.

Just wondering how st/xterm achieve strike-through... FWIW rxvt-unicode doesn't seem to support this feature either.
