The pair_content() function can be used to retrieve a color pair. The
foreground and the background color numbers are written to addresses
specified by the second and third parameters. While both parameters were
optional in older ncurses implementations (making it possible to pass
NULL pointers if the one does not care about either foreground or
background color), recent implementations seem to assume that both
parameters are valid pointers. Thus, instead of passing NULL, we need to
pass a pointer to a dummy variable when we do not care about the
background color.

To prevent from illegal memory access, we checked whether the list of
todo items is empty before performing an interactive todo item action
such as flagging or removal. However, since 1a4bf2b (Add a "hide
completed" view to the todo panel, 2016-01-17), it is possible to hide
completed items from the todo panel. Thus, it may occur that the todo
list box is empty while the list of todo items is not.
To detect such situations as well, teach todo_get_item() to return NULL
if the requested item does not exist. Then, instead of checking whether
the todo item list is non-empty, make sure that the item returned by
todo_get_item() is non-NULL when performing an action.
