[RFC/PATCH] Per branch properties for pull

It extracts all the information for pull from the config file.

If you have a config file as:

[branch "master"]
        remote=origin
        merge=next          #the remote name
        octopus=octopus
        twohead=recursive

When doing a "git pull" without extra parameters in the master branch it will fetch the origin remote repository and will merge the next branch (the remote name).

And you can also put the equivalent of the pull.{octopus,twohead} options for each branch.

This only changes the behavour when these keys exist and when git-pull is used without extra parameters.

Hi *,

   Now that we have the arbitrary keys in the config file...

   It does not affect the integrator that pulls from different
   places. I don't know exactly what is needed but just for discuss it
   could be something as:

[branch "master"]
        remote=net
        remote=ata
        merge=for-linus from ata
        merge=upstream from net
