+  # doesn't seem worth even a small amount of work to remove that dependency and
+  # support even older versions of Git.  So set that as the declared requirement
+  # for now.  In general, a reasonable approach might be to try to support the
+  # oldest version of Git in current "long-term support" versions of popular OS
+  # distributions.
