patch 8.0.0227: crash with ff=dos when first line in file has no CR
commit https://github.com/vim/vim/commit/2aa5f696b91a51f29873e340de4bdc182e1e8dd4

patch 8.0.0227: crash with ff=dos when first line in file has no CR
Problem: Crash when 'fileformat' is forced to "dos" and the first line in
the file is empty and does not have a CR character.
Solution: Don't check for CR before the start of the buffer.
