That is one way to do it.  However I don't think it is a good idea to
do this automatically every time.  I would rather see that it needs to
be done and the do it intentionally.  Usually I will do one whitespace
only cleanup with no other changes and do it first.  That way diff -b
or -w or -B or other combination will show as clean with no
non-whitespace changes.  And then I make the change I want to make.
If it is automatic then this mixes those two things both at the same
time.  I would rather see them distict.
