[Test case]
Connect to a x2go server on a session that has file sharing or audo-forwarding
enabled -> Error message "SCP: Warning: status code 1 received: scp:
~<user>/.x2go/ssh: No such file or directory" needs to be clicked away with
"ok".
[Regression potential]
Very low as the patch removes "~<user>" from the ssh string which is the same
as just using no path spec (":") as the default is the home dir of the logged
in remote user.
I have tested Graham's ppa packages and they work again as before the
libssh change and fix the bug reliably.

Bug description:
The recent CVE fix broke SCP support in libssh, which X2Go Client
(x2goclient) relies on.
Sessions now fail with error messages such as "SCP: Warning: status
code 1 received: scp: ~username/.x2go/ssh: No such file or
directory\n". (Also note the literal "\n" there, but I guess we don't
really need to care about that.)
The previous version worked fine and rolling the libssh4 package back
fixes this issue, but also leaves users vulnerable to the fixed
security issue in its scp implementation.
I've been looking at the debdiff, but spotting the actual changes is very
difficult due to the reformatting that was done at the same time. This degraded
the patch(es) into one big blob.
