OK.

Is this still TODO? As this one returns the prefix length (which
probably wants to be commented before the function) and this codepath
computes the prefix to cover the path to here, doesn't caller already
do the right thing?

Does this want to say "includeIf.path" instead? "include.path" is
done by handle_path_include() without involving a call to this
function.

Thanks.
