Making clear what the file contains is always a win.

I have one more suggestion:

Can we start documenting this stuff piece-by-piece under "Internals
Documentation" in the wiki?

We have a "Porting" section in the manual which could also do with
documentation.

I'd like to get into the habit of writing documentation at the same
time as accepting fixes.

A core C library lives and dies by documentation :-)

Cheers,
Carlos.
