I have verified that these are the only two options anywhere in the tree
that start with "no" and not "no-" so it should be pretty easy for
future options to conform on their own.  I don't see adding a comment
like this to every long option definition block to be very helpful, and
only adding it to initdb is just weird.  So I don't see the need for it.

I'm not quite sure how I got volunteered to do this work, but it's easy
enough so I don't mind.

Here is a new patch that emits a warning when --noclean and/or --nosync
are used.
