Bug#253743: /usr/bin/scp: scp foiled when input file grows during transfer

["Jeroen T. Vermeulen" <jtv@xs4all.nl>]

Package: ssh
Version: 1:3.8.1p1-4
Severity: normal
File: /usr/bin/scp

If data is appended to a file while it's already being scp'ed to another
location (e.g. because it's being transferred in from another host on a
faster connection), scp appears to ignore the part that was added after
startup.  The progress counter reaches 100%, which is 100% of the
partial file size, and stops there.
