+17.5 SSH over HTTPS proxy with more backends
+
+ The SSH based protocols SFTP and SCP didn't work over HTTPS proxy at
+ all until PR https://github.com/curl/curl/pull/6021 brought the
+ functionality with the libssh2 backend. Presumably, this support
+ can/could be added for the other backends as well.
