vim-patch:8.0.1819: swap file warning for file with non-existing directory

Browse Source 
Problem:    Swap file warning for a file in a non-existing directory, if there
            is another with the same file name. (Juergen Weigert)
Solution:   When expanding the file name fails compare the file names.
