syslog() produces bogus lines in /var/log/messages.
Testcase (with syslog-ng):
$ echo -e 'one\ntwo\nthree' | logger -t test
$ tail /var/log/messages
...

Dec 2 10:12:31 localhost test: one
Dec 2 10:12:31 localhost kernel:
Dec 2 10:12:31 localhost test: two
Dec 2 10:12:31 localhost kernel:
Dec 2 10:12:31 localhost test: three
I presume that the root of the problem is that the
writev(fd, { {"<PRI style="margin:0px;">", . }, { "MSG", . } }, 2)
used within syslog() sends "<PRI style="margin:0px;">" and "MSG" in two
separate datagrams to /dev/log.
