Re: [PATCH 1/2] git-remote-mediawiki: reset private ref after non-dumb push

> Git-mediawiki's "dumb push" sends the local revisions to the remote wiki,
> but does not update the local metadata to reflect the push (hence, the
> next pull will have to re-import the exported revisions).
>
> The previous implementation was simply omitting the update to the private
> ref after a dumb push. This was broken by 664059fb62 (Felipe Contreras,
> Apr 17 2013, transport-helper: update remote helper namespace), which
> does an automatic update of the private ref (not just the
> remote-tracking) on push.
>
> This patch fixes git-remote-mediawiki to reset the private ref after the
