[vtk-developers] git stupid question #4

OK. All is well with my build, but 

cd VTK
git checkout master
	(touches every file which is different)
git pull kitware master  
	(retrieve a couple of changes)
git checkout cscs-pv
	(touches every file which is different + new ones)
git merge master

make 
now make rebuilds practically all of VTK again even though only a couple of files were pulled. Imagine if vtkSetGet.h were different on the branches, now we'd really be in trouble!

Is there a way of saying
I'm on branch cscs-pv, please pull on the master branch from kitware, so that I can do a merge in a minute, without swapping my active branch?

Thanks
