+Test prefetching with no options works. The expectation is to prefetch the stuff
+required for working with the draft commits which happens to be only revision 5
+in this case.
+
+  $ rm -rf $CACHEDIR/master

+#if remotefilelog.true.shallowrepo.true
+The tree prefetching code path fetches no trees for revision 5. However, the
+file prefetching code path fetches 1 file for revision 5 and while doing so,
+also fetches 3 trees dealing with the tree manifest of the base revision 2.

+The tree prefetching code path fetches no trees for revision 5. And there is no
+prefetching of files in this test case.
