This message actually creeped me out the first time I read it, after 
writing an e-mail reply of my own[1].

The tone it`s written in, the points you make, and even the 
conclusion about "hg mg" -- as if you were reading my mind.

Yours was sent a bit before mine, but I guess we were writing it at 
the same time as well... Just spooky, lol.

That said, I totally understand what you`re talking about, and I gave 
an example of the desired (yet missing?) Git work flow here[2] :)
