| OK, this really sucks. diff has lost the -P option, that I've been
| relying on. Compare:
| http://www.freebsd.org/cgi/man.cgi?query=diff&manpath=FreeBSD+6.0-RELEASE
| http://www.freebsd.org/cgi/man.cgi?query=diff&manpath=FreeBSD+7.1-RELEASE
|
| It used to say:
|        -P     When comparing directories, if a file appears only in
the second
| 	      directory of the two, treat it  as  present  but	empty  in  the
| 	      other.
|
| Now it's gone. Regression?

What's wrong with -N?
