the file /etc/default/jenkins in the debian package has a line with a config value and a comment in the same line:

JAVA_ARGS="-Djava.awt.headless=true"  # Allow graphs etc. to work even when an X server is present

this leads to some problems regarding automation and also makes this harder to read. i would prefer to have all comments in seperate lines, for example:

# Allow graphs etc. to work even when an X server is present
JAVA_ARGS="-Djava.awt.headless=true"

please consider to change this.
