This seems to be the second patch only (the changes according to the
comments received).

Please combine all changes into a single patch, and do also include
a commit message that describes the overall change.

(To combine multiple patches into one, look at "git rebase --interactive"
and "squash")

Part of the reason we do this review dance is that we want patches that
are all "good in itself", not "need a second patch to fix the first one".

thanks,

gert
