I suspect it's not "that *are*" so much as "that *have*". I've seen a
number of submissions around the place where you have a certain amount
of substantive change, but also a good number of whitespace-only
changes in the same patch. It's just noise and unnecessary merge
One solution is to apply the patch, then run "git diff -w" or "git
diff -b". If the output is shorter than the original patch, raise a
warning. How you'd go about writing a PR bot to do this, though, I'm
not sure. Probably would need to maintain a local clone and stuff.
