It might indeed make sense to allow the user control over the -C
level, just as the user likely should have control over other
assumptions made by the script (to wit: $since = '5-years-ago';
$min_percent = 10). More fodder for future patches.

Now that I've read up more carefully on the -C option, I too wonder
why git-blame and git-show are invoked with different -C levels. At
the very least, I think they should be unified in this initial patch
to either one or two -C's. Since the script already is quite slow, I'm
leaning toward just one -C.
