Subject: [PATCH] multitail: pull pending upstream inclusion fix for
 ncurses-6.3

Without the fix build on ncurses-6.3 fails as:

    ui.c:1167:71: error: format not a string literal and no format arguments [-Werror=format-security]
     1167 |                                 mvwprintw(mywin -> win, 4 + loop, 42, dummy);
          |                                                                       ^~~~~
