Run winfsp-2.0.23075.msi.  Ctrl+C does not copy contents of app to 
clipboard (?).  I will transcribe manually:

     WinFsp2023 Setup
     Welcome ...
     -> Next

     WinFsp2023 Setup
     Custom Setup ...
     -> Next

     WinFsp2023 Setup
     Ready ...
     -> Install

Pop-up -- User Access Control -> Allow

     WinFsp2023 Setup
     Completed ...
     -> Finish

$ sshfs -h | head
WinFsp-FUSE options:
     -o umask=MASK              set file permissions (octal)
     -o FileSecurity=SDDL       set file DACL (SDDL format)

     -o uid=N                   set file owner (-1 for mounting user id)
     -o gid=N                   set file group (-1 for mounting user group)
     -o rellinks                interpret absolute symlinks as volume

So sshfs is connecting, but there are identity issues (UID/GID/SID) (?). 
  I tried a few guesses at options to allow write access, but without 
success.  Suggestions?
