I used this excellent answer to add a private git repo "Foo" as a dependency in a Node.js project "Bar" on Heroku.
Suppose I push an update to that repo Foo, but Bar is unchanged.
Is there a way to have Heroku update/pull Foo?
At the moment the only way I've found is to make a trivial change to to Bar, commit --amend --no-edit && push -f in order to keep a clean history.. There's surely a better way?
