share: reload repo after adjusting it in postshare() When sharing a repo that's using remotefilelog, the update that happens at the end of the `hg share` call does not see the remote repo path that's copied in hg.postshare(). This patch reloads the repo after hg.postshare() to address that. This changes a subrepo test case. Note that `hg share -U; hg co tip` worked there before, so I don't see see why `hg share` should fail. I also don't know what a "locally referenced subrepo". So maybe this is fixing a bug? Hopefully it's not breaking something someone actually cares about at least. Maybe someone who knows and cares about subrepos can review this.
