Subject: [PATCH] ncdc: pull upstream ncurses-6.3 fix

Without the change the build fails on ncurses-6.3 as:

    src/uit_dl.c:227:25: error: format not a string literal
      and no format arguments [-Werror=format-security]
      227 |     mvprintw(bottom, 0, hash);
          |                         ^~~~
