I fear this wording tweak doesn't go far enough.  The above
description seems to describe --topo-order just as well as
--date-order.

How about something like

		N_("topologically sort, maintaining date order where possible"),

?  I haven't checked the code to see if that's accurate, though.

Is the idea that:

 - by default, commits are listed in commit date order (newest first)

 - with --topo-order, they are topologically sorted in such a way as
   to ensure that in cases like

	---1---2---4---7
	    \           \
	     3---5---6---8

   (from git-log(1)), parallel tracks are not interleaved

 - with --date-order, they are topologically sorted but less
   aggressively, in particular matching commit date order in the
   usual case that that is already topologically sorted.

That would make --topo-order stronger than "show commits in
topological order" --- it should say something like "sort trying to
avoid breaking up lines of development".
