I was told that sshfs *does* handle .ssh/config. Turns out that sshfs
spawns "ssh -s sftp" to get a SFTP subsystem channel. Then it
directly implements the SFTP application protocol.
This way they don't need to link against libssh2. They spawn ssh with
a socketpair on stdin/stdout. They send/receive SFTP messages
directly.
The benefit is that everything works (options, host key handling, and
configuration files) like you'd expect from ssh/sftp/scp.
You may be tired of trying different alternatives, but perhaps
switching to this model is worth it. It would solve these
integration/user friendliness issues that a libssh2 implementation
has.
