For future patches:

1) Wrap at 72 characters, your commit message is using shorter line
   lengths.

2) Don't both with file numbers, they change all of the time. Digging
   out an old commit with line numbers isn't very useful, you'd have to
   rewind your tree for them to make sense.

I'll commit this, but rewrite the commit message somewhat.
