jottacloud: avoid double url escaping of device/mountpoint - fixes #4697

Before this change we counted the final summary error as an error,
producing confusing log messages like:

    Failed to check with 54 errors: last error was: 53 differences found

This change marks the summary error as already being counted, so the
error message becomes:

    Failed to check with 53 errors: last error was: 53 differences found

This change also returns a listing failure in preference to a summary error.

 If you set the `--sftp-ask-password` option, rclone will prompt for a
 password when needed and no password has been configured.
 
+If you have a certificate then you can provide the path to the public key that contains the certificate.  For example:
+
+```
+[remote]
+type = sftp
+host = example.com
+user = sftpuser
+key_file = ~/id_rsa

+
+Note: the cert must come first in the file.  e.g.
+
+```
+cat id_rsa-cert.pub id_rsa > merged_key
+```
+
+### Host key validation ###
+
+By default rclone will not check the server's host key for validation.  This
+can allow an attacker to replace a server with their own and if you use
+password authentication then this can lead to that password being exposed.
+
+Host key matching, using standard `known_hosts` files can be turned on by
+enabling the `known_hosts_file` option.  This can point to the file maintained
+by `OpenSSH` or can point to a unique file.
+
+e.g.
+
+```
+[remote]
+type = sftp
+host = example.com
+user = sftpuser
+pass = 
+known_hosts_file = ~/.ssh/known_hosts
+````
+
+There are some limitations:
+
+* `rclone` will not _manage_ this file for you.  If the key is missing or
+wrong then the connection will be refused.
+* If the server is set up for a certificate host key then the entry in
+the `known_hosts` file _must_ be the `@cert-authority` entry for the CA
+* Unlike `OpenSSH`, the libraries used by `rclone` do not permit (at time
+of writing) multiple host keys to be listed for a server.  Only the first
+entry is used.
+
+If the host key provided by the server does not match the one in the
+file (or is missing) then the connection will be aborted and an error
+returned such as
+
+    NewFs: couldn't connect SSH: ssh: handshake failed: knownhosts: key mismatch
+
+or
+
+    NewFs: couldn't connect SSH: ssh: handshake failed: knownhosts: key is unknown
+
+If you see an error such as
+
+    NewFs: couldn't connect SSH: ssh: handshake failed: ssh: no authorities for hostname: example.com:22
+
+then it is likely the server has presented a CA signed host certificate
+and you will need to add the appropriate `@cert-authority` entry.
+
+The `known_hosts_file` setting can be set during `rclone config` as an
+advanced option.
