-git push origin :::
+`git push origin :`::
        Push "matching" branches to `origin`. See
        <refspec> in the <<OPTIONS,OPTIONS>> section above for a
        description of "matching" branches.
 
-git push origin master::
+`git push origin master`::
        Find a ref that matches `master` in the source repository
        (most likely, it would find `refs/heads/master`), and update
        the same ref (e.g. `refs/heads/master`) in `origin` repository
        with it.  If `master` did not exist remotely, it would be
        created.
 
-git push origin HEAD::
+`git push origin HEAD`::
        A handy way to push the current branch to the same name on the
        remote.
 
-git push origin master:satellite/master dev:satellite/dev::
+`git push origin master:satellite/master dev:satellite/dev`::
        Use the source ref that matches `master` (e.g. `refs/heads/master`)
        to update the ref that matches `satellite/master` (most probably
        `refs/remotes/satellite/master`) in the `origin` repository, then
        do the same for `dev` and `satellite/dev`.
 
-git push origin HEAD:master::
+`git push origin HEAD:master`::
        Push the current branch to the remote ref matching `master` in the
        `origin` repository. This form is convenient to push the current
        branch without thinking about its local name.
 
-git push origin master:refs/heads/experimental::
+`git push origin master:refs/heads/experimental`::
        Create the branch `experimental` in the `origin` repository
        by copying the current `master` branch.  This form is only
        needed to create a new branch or tag in the remote repository when
        the local name and the remote name are different; otherwise,
        the ref name on its own will work.
 
-git push origin :experimental::
+`git push origin :experimental`::
        Find a ref that matches `experimental` in the `origin` repository
        (e.g. `refs/heads/experimental`), and delete it.
 
-git push origin {plus}dev:master::
+`git push origin {plus}dev:master`::
        Update the origin repository's master branch with the dev branch,
        allowing non-fast-forward updates.  *This can leave unreferenced
        commits dangling in the origin repository.*  Consider the
