Recent ncurses can be configured --with-termlib, which splits out the terminfo-level functions from libncurses into a separate libtinfo. This allows us to avoid an unnecessary dependency on libncurses. (We already avoided this on distributions that link with -Wl,--as-needed.) Signed-off-by: Anders Kaseorg <andersk@mit.edu>
