New Revision: 272217
URL: http://svnweb.freebsd.org/changeset/base/272217
Log:
Update the usage message and the man page to account for the new long
options. Bump the version number to 20140927.
While here, use explicit fputc() calls to skip a line in the output.
This to avoid having to hunt for extra '\n' characters in the printf
format strings.
