Say a local commit publishes nothing (#129)

The local driver sometimes ran `git commit` itself instead of calling
finish_milestone, then told the operator a PR was waiting when none had
been opened. A commit still runs (it's contained, and publishing takes
whatever is there), but when the driver's command commits anywhere in
its line, the harness adds to its result: committed locally only;
nothing is published until finish_milestone, and there is no PR until
then. Structural, at the moment the model would draw the wrong
conclusion (P6), rather than left to it noticing.

Closes #129
