Yes. Fun fact: the right combination of format flags makes git segfault!

The history was massively streamlined to get fewer merge commits and git 
no longer core dumps when rendering the full thing with the proper 
flags.

Another fun fact, we have merge commits in the repo with upwards of 6 
parents or so.

   glog = log --graph --pretty=format:'%Cred%h %C(green)%t %Creset -%C(yellow)%d%Creset %s %Cgreen(%an, %cr, %ad)%Creset' --date=short
   gnlog = log --graph --pretty=format:'%Cred%h %C(green)%t %Creset %C(red)%ad %Creset-%C(yellow)%d%Creset %s %n      %N %-GG' --date=short


% git gnlog
<hit G>
<it shows first commit>
% git glog
<hit G>
error: git died of signal 11
<it shows commits from the 2003-01-26 timeframe>

Someone™ should debug that ...
