 --merge-base::
-       Instead of showing the commit list, just act like the
-       'git-merge-base -a' command, except that it can accept
-       more than two heads.
+       Instead of showing the commit list, determine possible
+       merge bases for the specified commits. All merge bases
+       will be contained in all specified commits. This is
+       different from how linkgit:git-merge-base[1] handles
+       the case of three or more commits.
