+3.9. sftp: Extension request "expand-path@openssh.com"
+
+This request supports canonicalisation of relative paths and
+those that need tilde-expansion, i.e. "~", "~/..." and "~user/..."
+These paths are expanded using shell-like rules and the resultant
+path is canonicalised similarly to SSH2_FXP_REALPATH.
+
+It is implemented as a SSH_FXP_EXTENDED request with the following
+format:
+
+	uint32		id
+	string		"expand-path@openssh.com"
+	string		path
+
+Its reply is the same format as that of SSH2_FXP_REALPATH.

+This extension is advertised in the SSH_FXP_VERSION hello with version
