Yeah, with git, rather than cd'ing to another directory, you'd just do  
`git checkout rel8_3` and work from the same directory.

For better or for worse, because git is project-oriented rather than  
filesystem-oriented, you can't commit to all the branches at once. You  
have to commit to each one independently. You can push them all back  
to the canonical repository at once, and the canonical repository's  
commit hooks can trigger for all of the commits at once (or so I  
gather from getting emails from GitHub with a bunch of commits listed  
in a single message), but each commit is still independent.

It has to do with the fundamentally different way in which Git works:  
snapshots of your code rather than different directories.

Best,
