// here is the deal -- git pull is pretty complex with

// A) specify the remote branch you want to
// merge & fetch, in which case it completely
// ignores the properties of branch you are on, or
//
// B) specify no args, in which case it figures out
// the branch to fetch from the remote tracking
// and merges those in.
// so lets switch on A/B here
