messages of the first commit and of those with the "squash" command,
but omits the commit messages of commits with the "fixup" command.
+If you want to update a ref to point to a rewritten commit, add a
+command "ref <refname>" after the "pick", "edit", or other command
+that produces the commit.
+
'git rebase' will stop when "pick" has been replaced with "edit" or
when a command fails due to merge errors. When you are done editing
and/or resolving conflicts you can continue with `git rebase --continue`.
