Why? How is this better now? I'm sure there is a good reason why you add
this but we don't know as the commit tells nothing we don't already know
just from looking at the patch.

The most important part of commit log is to answer the question "Why?",
not "What?".

Unnecessary style change, please drop.

Oh, and USE capitalisation, punctuation and so on in the commit log. It
will be archived to git.
