 means "list all the commits which are included in 'foo' and 'bar', but

 OPTIONS
 -------
 --pretty::
        Print the contents of the commit changesets in human-readable form.
 
+--header::
+       Print the contents of the commit in raw-format; each
+       record is separated with a NUL character.
+
 --objects::
        Print the object IDs of any object referenced by the listed commits.
        'git-rev-list --objects foo ^bar' thus means "send me all object IDs
        which I need to download if I have the commit object 'bar', but
        not 'foo'".
 
+--unpacked::
+       Only useful with `--objects`; print the object IDs that
+       are not in packs.
+
 --bisect::
        Limit output to the one commit object which is roughly halfway
        between the included and excluded commits. Thus, if 'git-rev-list

+--max-count::
+       Limit the number of commits output.
+
+--max-age=timestamp, --min-age=timestamp::
+       Limit the commits output to specified time range.
+
+--sparse::
+       When optional paths are given, the command outputs only
+       the commits that changes at least one of them.  This
+       flag makes the command ignore the paths, outputting all
+       eligible commits (still subject to count and age

+
+--all::
+       Pretend as if all the refs in `$GIT_DIR/refs/` are
+       listed on the command line as <commit>.
+
+--topo-order::
+       By default, the commits are shown in reverse
+       chronological order.  This option makes them appear in
+       topological order (i.e. descendant commits are shown
+       before their parents).
+
 --merge-order::
        When specified the commit history is decomposed into a unique
        sequence of minimal, non-linear epochs and maximal, linear epochs.
