Subject: [PATCH] Windows native OpenSSH fix

Windows native OpenSSH has alternative behavior for standard I/O
descriptors, which can be selected through the OPENSSH_STDIO_MODE
environement variable. Setting it to "nonsock" is required for
sshfs compatibility.

See https://github.com/PowerShell/openssh-portable/pull/759
for details.
