Rclone mount blomp problem

Thank's a lot! Just one more thing related to blomp or swift base backends (?): currently the about command is not supported.

rclone --config=/etc/rclone/rclone.conf -vv about Blomp:

The about command does not work with blomp-swift:email@example.com
Is it actually supported by the api of blomp?
