    patch 8.0.0159: crash on startup when updating tabline

    Problem:    Using a NULL pointer when using feedkeys() to trigger drawing a
                tabline.
    Solution:   Skip drawing a tabline if TabPageIdxs is NULL. (Dominique Pelle)
                Also fix recursing into getcmdline() from the cmd window.
