Add "two line" mode to show commit msg on 2nd line

[garyo]

Thanks for ogl, I'm using it all the time now and I love it!
The only thing I'm missing is sometimes it truncates branch info that I need.

I use something like this for my git ll config:

alias.ll=log -10 --graph --date-order --format=twolines
pretty.twolines=tformat:%h %an, %cr: %d%n. . . . %w(70,0,8)%s

% git ll

the nice thing about this is you can see all the branches that each commit is part of, even if the branch names are long. Any chance you could add a "two-line" mode like this, but with the amazing prettiness that OGL has?
