Along the same lines as this question - How do I clone all remote branches with Git?, if I have set up a Github repository like so:
$ git clone git@github.com:viatropos/spree.git mycart
$ cd mycart
$ git branch
* master
$ git remote add origin git@github.com:viatropos/mycart.git
fatal: remote origin already exists.
$ git remote add myfork git@github.com:viatropos/mycart.git
$ git branch -a
* master
origin/0_8_5
origin/0_9_2
origin/494-rake-task-for-default-data
origin/598-ruby-19
origin/611-refactor-charges-to-use-calculators-and-be-polymorphic
origin/811-refactor-payment-gateways
origin/HEAD
origin/master
origin/nested_attributes
origin/slicehost
origin/taxonomy_landing
origin/v9_592_tmp
$ git checkout -b slicehost origin/slicehost
Branch slicehost set up to track remote branch refs/remotes/origin/slicehost.
Switched to a new branch "slicehost"
$ git branch
master
* slicehost
... How do I make it so the original git@github.com:viatropos/spree.git project ignores anything in the vendor/extensions directory, while the git@github.com:viatropos/mycart.git project doesn't, given there's only this one main project/directory (mycart)?
