Just indentation of the inner include blocks. The preprocesor directives
are usually indented by spaces between the # and the keyword such as:
#ifdef ...

This is missing from the commit message. Imagine that you are trying to
figure out why this change was needed, without a proper description in
the commit message this will take hours to figure out.

Ok, this explanation should be in the commit message so that anybody who
looks at the commit can figure out why the numbers were changed this
way.
