I could reproduce it with Emacs 26 on MS Windows.

Well, the problem is the syntax of local file names on MS Windows, like
"c:/DOCUME~1/Zaretzky/LOCALS~1/Temp/shadowfile-testsSe3Hgz". shadowfile
uses cluster file names with syntax "/<cluster name>:<local file name>".
If the <local file name> starts with a volume letter, the resulting
string looks like a remote file name, and shadowfile is confused.

Fixing this is not trivial. Is it worth to do it? Again, I doubt that
shadowfile has worked ever on MS Windows; I believe it would be
sufficient to document this restriction.

Best regards, Michael.
