I would just say about the examples that often it's better if they are
completely stand-alone (since we want people to copy and adapt the
code).  That would imply not using the common/ header file, but either
inlining the function or using a less efficient but simpler loop.
This is also the reason why the examples don't #include <config.h>

Anyway the patch is fine, but IMO could be improved as above.

ACK.
