Aren't you screwing up indentation here? It looks wrong both in my
mail client's view and on the list archives, whereas. Furthermore
this is code you've introduced earlier in the series, so it should
be got right there, not here.

Please fix the comment style as a whole, not just the stray trailing
blank.

Here you again seem to be screwing up correct indentation. There are
more such instances, so I guess I'll leave it to you to go over the
whole patch once more.
