- quilt/diff.in, quilt/refresh.in: stop using /dev/null for added

  or removed files: GNU diff does not do that either, and for
  removed files this leads to headers that only reference
  $file.orig and /dev/null, so the actual file is not found. (This
  is only truly fixes -p0 style patches as -p1 style patches use
  dir.orig/file instead of dir/file.orig so the filename is not
  lost, but stopping to use /dev/null makes sense for -p style
  patches just the same.
- files command: remove a redundant find_patch().
- Make top_patch() fail if there is no top patch.
