Whitespace changes are "by definition" gratuitous.  We don't disallow
them, but they should be limited to the lines that are changed for other
reasons as well.
[ Note also that there are degrees: e.g. reindentation is not 100%
  gratuitous, contrary to tabify/untabify.  ]

This is yet elsewhere on the scale of "gratuitous", so we also prefer to
refrain from doing so, but sometimes it's justified (usually together
with a string of other, more substantial, changes).
