0.3.4.x? I would prefer to have this branch merged into 0.3.4, since it is
just a control port field accounting fix.

> Different ticket and patch please! This one is clearly a bug;
disallowing 0-length data cells entirely seems more contentious, possible
requires a spec change, and has a higher possibility of breaking things.
+1 on a different ticket and patch; and if we do it, we need to figure out
how we're handling the fingerprinting issue.
