>Description:
The logger command seems to inject an extra CR for each line of stdin, when -s is used. In some cases it can be corrected with input, however it is probably not the correct behavior...

srv-63b7# echo blah | logger -s -t "title"
title: blah

srv-63b7# echo -n blah | logger -s -t "title"
title: blah
srv-63b7# cvs update -dP | logger -s -t "title"
...

The extra CR per line does not appear in syslog messages.
