-to decide in any particular way.
+
+"git-merge-base" finds as good a common ancestor as possible between
+the two commits. That is, given two commits A and B 'git-merge-base A
+B' will output a commit which is reachable from both A and B through
+the parent relationship.

+Given a selection of equally good common ancestors it should not be

 The "git-merge-base" algorithm is still in flux - use the source...
