+@code{git format-patch} accepts a wide range of
+@uref{https://git-scm.com/docs/gitrevisions, revision range} specifiers.
+For example, if you are working in a branch, you could select all commits
+in your branch starting at @code{master}.

+@example
+$ git format-patch master..@var{MY_BRANCH} -o outgoing \
