I never quite understood what they're for--do they add any information
not already available in the history? If not, and if people still find
them helpful anyway, then I dunno, it looks like a sign of some sort of
failure of our history display tools.
I don't think they add much in the case of a graphical viewer, but for
"git log", it does make it look nicer..
Especially if you do "git log --first-parent" ;-).
