I've pushed this series many thanks.

For this last one, I've renamed "topic_change_source" to 
"_rewrite_noise" (because I'm not sure behing command specific make 
sense here). I'm not fully convinced by the new name, but we can 
re-adjust this later if needed.

I've also pushed a fix for the working copy lagging behind have `hg 
topic --rev . foo`.

Cheers,
