vim-patch:8.1.0362: cannot get the script line number when executing a function

Problem:    Cannot get the script line number when executing a function.
Solution:   Store the line number besides the script ID. (Ozaki Kiichi,
            closes vim/vim#3362)  Also display the line number with ":verbose set".
