After a lot of tests I've found the solution:

I'm creating the patch with:

$ diff -Naur -X exclude nn-6.7.3 nn-6.7.3.patched > diff

while having in 'nn-6.7.3' a 'make clean' version of the original
tree and in 'nn-6.7.3.patched' a 'make clean' version of my modified
source tree; the exclude file just says:

$ cat exclude
*.orig

i.e. excludes the files *.orig which I also have in 'nn-6.7.3';

the trick is applying the patch as:

$ cd /usr/ports/news/nn/work
$ patch -p0 < ../.mywork/diff

i.e. using the -p0; without -p0 the new files end up in the current
directory, while with -p0 they get created in the right place. I've
read the man page of patch again and again; it explains the function
of -pN but not this effect :-(
