patch 7.4.1961
Problem:    When 'insertmode' is reset while doing completion the popup menu
            remains even though Vim is in Normal mode.
Solution:   Ignore stop_insert_mode when the popup menu is visible.  Don't set
            stop_insert_mode when 'insertmode' was already off. (Christian
            Brabandt)
