Re: [JGIT PATCH 6/5 v2] Add tests for RevWalk and its supporting code

A few /09 interesting/ places in StartGenerator are not covered by the tests.

		if (q instanceof DateRevQueue)
			pending = (DateRevQueue)q;
		else
-->			pending = new DateRevQueue(q);

and

		if (tf != TreeFilter.ALL) {
-->			rf = AndRevFilter.create(rf, new RewriteTreeFilter(w, tf));
-->			pendingOutputType |= HAS_REWRITE | NEEDS_REWRITE;
		}

PendingGenerator
						if (n != null && n.commitTime >= last.commitTime) {
							// This is too close to call. The next commit we
							// would pop is dated after the last one produced.
							// We have to keep going to ensure that we carry
							// flags as much as necessary.
							//
-->							overScan = OVER_SCAN;

I'll merge it anyway since this is still a huge improvement compared to the previous state.
