How to tell revlog and revlogng apart

[Wujek Srujek]

Hi. Ok, I'll look in the code.
But I think you got me wrong: I am not trying to write a mercurial clone; I
am trying to learn a bit of python while getting to know mercurial (a tiny
bit) better from the inside - and all I am doing is to write some code to
read the revlogs (dirstate was too easy). It is better than 'hello, world',
so I wouldn't consider it a waste of my time, though, you are being a
little harsh here ;d
