Offering hg log -G by default?

[Arne Babenhauserheide]

Hi, 

I’m currently doing some revising of the guide on mercurial.selenic.com, and since I want to use only core commands, I experienced quite painfully how useful the graphlog-extension is to visualize changes. 

Would it be possible to make the -G flag to hg log part of core? This should not have any negative effect on the user-interface, but it would enable users of an unconfigured Mercurial to get topology information on their history. And that’s something I consider a core-feature with branchy history (the default for people who do not use extensions). 

Is there a specific reason for not having that already?

Best wishes, 
Arne
