More than one line range can be related and of interest to a forensics/archeology task. In a simple multi range case, you'd have 2 line ranges in the same file that you want to see the history and graph of. Such as 2 related macro definitions in a header file. In a complex multi range case, you'd have many line ranges spread over multiple blobs and some of the blobs have disjoint commit graphs. The complex multi range case may be too much for a GSOC project, and the simple multi range case may be also. However, the command syntax should be general enough to handle them without being too ugly so that the implementation could be improved and expanded later.
