I think you're all speculating too far. It says it will purge 'one or
more packages specified via regex(7), glob(7) or exact match'. So if you
specify none, I expect it will purge none.

Oh, and 'purge is identical to remove except that packages are removed
and purged (any configuration files are deleted too)'. It doesn't JUST
remove config files.
