Greg, there probably isn't any problem with his syslog.

Running together of messages without terminating newlines
did used to happen though until commit
5fd29d6ccbc98884569d6f3105aeca70858b3e0f
("printk: clean up handling of log-levels and newlines")
changed behavior so that newlines are emitted if necessary
before every "<.>" loglevel but "<c>".

That means that adding trailing newlines to pr_<level>
calls aren't _really_ necessary unless the pr_<level>
is followed by a bare printk without KERN_<LEVEL>.

I still think it's better from a style perspective to keep
adding terminating newlines until most all of the printks
are converted to pr_<level>.
