DragonFly-supfile change

["Justin C. Sherrill" <justin@xxxxxxxxxxxxxxxxxx>]

Is there any objection to changing the default cvsup file to grab the
checked out version of sources?  I'm working on the Updating portion of the
handbook, and I'm realizing that having to check out the source is an extra
unneeded step for most users.  This also would be 'expected' behavior for
users coming from FreeBSD.
