openssh/openssh-CVE-2019-6109-force-progressmeter-update.patch

commit bdc6c63c80b55bcbaa66b5fde31c1cb1d09a41eb
Author: dtucker@openbsd.org <dtucker@openbsd.org>
Date:   Thu Jan 24 16:52:17 2019 +0000

    upstream: Have progressmeter force an update at the beginning and
    
    end of each transfer.  Fixes the problem recently introduces where very quick
    transfers do not display the progressmeter at all.  Spotted by naddy@
