missing patch comments should not be classified as an error

[John Marino <netbsd%marino.st@localhost>]

I don't know when this changed, but I just installed the latest pkglint 
to clean up a makefile and it's reporting a missing comment on a patch 
as an error.

While I've softened my stance on patch comments in recent weeks, I can 
not agree that a patch lacking a comment constitutes an error.  That's a 
bit too draconian.  Many of these patches are very old and many others 
frankly don't need a comment.

Can we get this put back to a warning?
