Emacs 25 + Mercurial 3.8

Finally achieved!

With Emacs 25 and Mercurial 3.8 the improvements in vc-hg.el are nice. And really nice with some customization.

Default view:

Custom the .emacs configuration:

(custom-set-variables
'(vc-hg-log-switches (quote ("--graph"))))

Custom the .hgrc configuration:

[experimental]
graphshorten = yes

And you get:

Cool!
