vim-patch:8.0.0548: saving the redo buffer only works one time (#8629)

Problem:    Saving the redo buffer only works one time, resulting in the "."
            command not working well for a function call inside another
            function call. (Ingo Karkat)
Solution:   Save the redo buffer at every user function call. (closes vim/vim#1619)
