Well, I'll need to read through my IRC logs when I get into the office

Ok... so I think my mental model is restructuring itself, thanks.

Yeah, bisecting and clean history is mainly what I'm concerned about.
Check out how xorg-server-1.6-apple paralleled server-1.6-branch:
git log --graph --pretty=oneline
(7c16b68ab879f5b4b1aedfc6b2aadbe56193dd19 was the server-1.6 branch
from master ... I'm sure there's some clever way to say that in git
syntas, but meh... I'm just no that cool.)
For this branch, I just committed cherry-picks and merged origin/
server-1.6-branch ... there are a lot of long parallel tracks which
would make bisecting problematic. I'm not even sure how bisection in
git works without a linear model. My guess is that it just bisects
along the main branch and sees the merge commit as a single

Yeah, that makes sense based on how I now understand things. origin/
master is not any more special than bond007/master in this scenario.
Both are published and can't be altered. The merge commit just after
each of those is essentially the union of the two and thus the most
recent commit that needs to be unaltered.

Ah... interesting. git is certainly clever if not confusing...
