# Git Only: Perform a Git operation only when in a whitelisted directory.
#
# This is really only useful when combined with git-gat. For instance, let's 
# say we want to create a branch in two of our side-by-side repos, we can say:
#
# git gat only Repo1 Repo2 -- checkout -b feature1
#
# This will create and checkout a branch called feature1, but only in Repo1 and Repo2.

# Git Gat: The Git Gatling Gun!
# Perform operations machine-gun style on side-by-side git repositories.
#
# Save this somewhere on your path as git-gat (or whatever you want to call it).
# Usage:
#
# git gat status
# git gat -f status # Perform operation even if the repo is dirty.

The reason this does not return a value is that SequenceType
is very general. It has no methods for modifying the sequence,
only traversing it.

Instead, we pass our "unique" method a closure that tells it
how to add a value to our result. The result is not visible 
at all to this method. It is captured by our closure.

The reason we don't pass the result as a parameter is because it
