Summary: BSD diff(1) compares same files and dirs

patch
I was wondering why a "diff -rq" on FreeBSD-12 (BSD diff) ran endlessly while
on FreeBSD-11 (GNU diff) it terminated in 0.6 seconds.
This is because BSD diff compares files and dirs even if they are the same. I
checked what GNU diff does in this case and added the corresponding code to
diffdir() and diffreg(). The style is probably considered bad ;-).
