recursive sftp transfers abort when destination dir exists

[Simon Déziel]

Since I moved from Trusty to Xenial, my sftp backup script stopped working. After a bit of investigation it seems to be exactly https://bugzilla.mindrot.org/show_bug.cgi?id=2528. Fortunately it was fixed in OpenSSH 7.2.

I know 7.2 is pretty recent and not yet in Debian but I would appreciate if Xenial could have a fix for this annoying bug. If upgrading to 7.2 is not possible, a backport of the specific commit would also be appreciated.

Thanks in advance.
