I think fixing a stylistic issue in code that's being edited for other
purposes is fine, and a good idea going forward.  We wouldn't commit a
patch that would *only* fix those, because that would cause a problem
for backpatches for no benefit, but if the patch touches something else,
then a backpatch of another patch is going to need manual intervention
anyway.
