Make sure this historgram gets properly marked as deprecated in any XML files
which refer to it.  Ping mpearson if you're not sure where to look.

There is no line in histograms.xml which corresponds to this histogram.
According to the original change which added this line, this histogram is
intended to appear only on about:histograms locally.
