Sean Owen commented on SPARK-3850:
----------------------------------
Yeah, does anyone know how to do that? this one seems like one I could live
without... trailing whitespace doesn't do anything and might make people go
nuts tracing down all the failures because their IDE added some spaces. However
we do want to avoid spurious whitespace changes. They show up in the git diff,
so we can detect them. It's not common for someone's tool to stick in
whitespace at the end of a line, so it's not a frequent problem. Maybe that's
enough?
