vim-patch:8.1.0320: too much 'incsearch' highlight for pat matching everything

Browse Source 
Problem:    Too much 'incsearch' highlight for pattern matching everything.
Solution:   Add the skiplen to the command and remove the line range.
            (Christian Brabandt)  Check for empty pattern earlier.
