#systemd IRC log discussing issue

On CoreOS I'm running Java apps in Docker and logging to stdout.
Large logs (eg. stacktraces) get split over multiple lines which is far from
ideal.

This only seems to affect logs passed in via fd as discussed in IRC (attached)
and not those sent to the journald socket.

Quick testcase Docker app at: 
https://github.com/stuart-warren/testbigdockerlogs

Or:

``perl -e "print 'a'x4096, 'b'" | systemd-cat``
