Committed, thanks!

Committed, with a minor change: the extra function doesn't seem to be
necessary, the parameter can just be marked as unused.  Thanks!

This one also looks good, but since it's more involved, I'll play with
it a bit more before committing it.  I suspect a lot of the
signed/unsigned things can be resolved without adding casts, by making
the loop variables unsigned, since they usually range only from 0 to
some positive integer anyway.
