Trailing whitespaces can lead to pointless conflicts when applying
patches.  See, e.g.,
http://www.mail-archive.com/libvir-list@redhat.com/msg04896.html .

In this thread, the project’s policy is to get rid of them, and
‘show-trailing-whitespace’ in ‘.dir-locals.el’ or similar would
definitely help.

Thanks,
