MarkerClusterer fails to cluster at max map zoom level

[GoogleCodeExporter]

What steps will reproduce the problem?
0. Create a marker clusterer with no max zoom option
1. Create several markers at exactly the same latlng
2. Zoom the map to its maximum resolution where the markers are
3. At the maximum resolution, markers are not clustered

What is the expected output? What do you see instead?

Markers should be clustered at any resolution level if no max zoom option 
is selected.

What version of the product are you using? On what operating system?

Tested on development version. I am attaching a modified simple-example.htm 
of marker clusterer that shows the error.

Please provide any additional information below.

It can be solved by changing the following lines in the redraw_ function of 
marker clusterer:

    var mz = markerClusterer.getMaxZoom_();
    if (mz === null) {
      mz = map_.getCurrentMapType().getMaximumResolution();
    }
    if (zoom_ >= mz || this.getTotalMarkers() === 1) {

to

    var mz = markerClusterer.getMaxZoom_();
    if (mz === null) {
      mz = map_.getCurrentMapType().getMaximumResolution();
    }
    if (zoom_ > mz || this.getTotalMarkers() === 1) {

or just

    var mz = markerClusterer.getMaxZoom_();

    if ((mz !== null && zoom_ >= mz) || this.getTotalMarkers() === 1) {

Fixed in r1017. For some reason the svn log command did not update the issue's 
status.
