patch 8.1.1371: cannot recover from a swap file

Problem:    Cannot recover from a swap file.
Solution:   Do not expand environment variables in the swap file name.
            Do not check the extension when we already know a file is a swap
            file.  (Ken Takata, closes 4415, closes #4369)
