The usage message is followed by three new line characters, the 1st is
embedded in the last line of the usage message, the second is output
by the print function, and the third by the leading new line character
in the separator string.
All other sections use two trailing new line characters instead.
If the formatting of this section is desired to be consistent with all
the other sections, this print function may be substituted with the
printf function, which does not append a new line character to its
argument.

Other than that, LGTM. Thanks.
