                 Callers most commonly need to iterate backwards over the history
                 it is interested in.  Doing so has awful (quadratic-looking)
                 performance, so we use iterators in a "windowed" way.
                 We walk a window of revisions in the desired order.  Within the
                 window, we first walk forwards to gather data, then in the desired
                 order (usually backwards) to display it.
                 This function returns an (iterator, getchange) pair.  The
                 getchange function returns the changelog entry for a numeric
                 revision.  The iterator yields 3-tuples.  They will be of one of
                 the following forms:
                 "window", incrementing, lastrev: stepping through a window,
                 positive if walking forwards through revs, last rev in the
                 sequence iterated over - use to reset state for the current window
                 "add", rev, fns: out-of-order traversal of the given file names
                 fns, which changed during revision rev - use to gather data for
                 possible display
                 "iter", rev, None: in-order traversal of the revs earlier iterated
                 over with "add" - use to display data'''
