We normally tend to categorize guestrepos using their canonical path. And, If there are hundreds of guestrepos, we tend to work with a bunch of guestrepos that are grouped under a single canonical path. And we might want to grpull, grupdate only those guestrepos grouped under a given canonical path.
Updated matchguests function to match any path rather than just guestrepo paths.
