changeset_printer: use node.wdirrev to calculate meaningful parentrevs
Because we defined the working-directory revision is INT_MAX, it makes sense
that "hg log -r 'wdir()'" displays the "parent:" field. This is the same for
two revisions that are semantically contiguous but the intermediate revisions
are hidden.
