Agreed! And since I am going to make some changes in lazyinit code anyway,
I can very well make that change (and of course give Robin the credit for
it:).

On the other hand I do not see a *huge* problem with commits like that, but
it is just additional unnecessary commit. Usually people complain that
git blame need some more digging with commits like this changing
otherwise perfectly sane code, but when one is going to make that change
when making some changes "at that area" it would mess up git blame
anyway.

Thanks!
