If one day Peter decides that "staging" is not a cool name anymore and use a
different name for the branch :) we should account for that and make it a
variable, possibly even parametrize this function with it.

"There's no local branch named 'staging'" would IMO be more descriptive, so as
not to confuse it with staging in git.

Code-wise looks OK to me, but since I don't know what Peter's requirements
on/expectations of this script are, I can't do a more thorough review.
