I once had someone make me re-write a commit message four time just as a
kind of bullying and then at the end he was like, "You said NULL
dereference instead of NULL pointer dereference so I had to re-write the
commit message and I added some comment to the kernel git log explaining
how you suck."  So these days I have made it a rule that if you're going
to complain about commit messages then you have to write your own for
people to cut and paste.  Otherwise people are like, "You're too stupid
to read my mind.  LOL.  Do it again."

But in this case the commit message is fine.  The key things with a
commit message are:

1) What's the motivation
2) What's the effect for the user
3) Are all the surprising aspects are explained.  Do I have enough
   information to review it quickly.

Removing wrappers is the motivation.  No need to explain that further.
No effects for the user.
There were no surprising bits.

It's fine.
