The "git blame" command will show you the history of lines *currently*
in the file as of the blamed version.  If you want to see the reverse,
do this:

  git blame --reverse dc7a10..6cdfac --  Modules/Registration/HighDimensionalMetrics/include/itkImageToImageObjectMetric.hxx

That will show the lines as they appeared in dc7a10 but annotated with
the commit in which they last existed.  For lines that still exist it
will show 6cdfac.  For lines that were removed you will see the hash
of the last commit that still had the lines.  In this case that is
2f8eff, the parent of 6cdfac.
