C style guide

[Mark Brader]

The revised Indian Hill style guide recently posted here is excellent
in many respects, but the example function copy() in section 14 contains
no fewer than four bugs, of which three are in the same line.  Here's a
patch which I have tested and which fixes all of them.  Finding them
without reading the patch is left as an exercise for the reader.

Patch follows:
