Exactly.  I tried to track the main Linus repository and Jeff Garzik's
netdev in one place.  Then I discovered that my repository if full of
unintended merges made by "stg pull".

First of all, using "origin" on every line carries to little
information.

Secondly, I think the relationship should be between a local development
branch and a local tracking branch.  After all, all remote data is
placed on a local tracking branch first.  It's better not to jump over
layers of abstraction.  Suppose I want to update "masterB".  I tell git
to sync "originB" first.  git already has rules what to do if it should
sync "originB".  Let's not supersede those rules.

I would write the config like this:

[branch-upstream]
master = linus
ata-irq-pio = irq-pio
ata-pata = pata-drivers

Sorry, I don't understand this part.
