     This is handy for determining whether two different pattern paths are on the same filesystem

+
+    This function only considers the start of a pattern's path—from the start of the path up until

 This same order of execution extends to multiple repositories and/or

+Based on the above, you can see the difference between, say, an `after: action`
+hook with `states: [fail]` and an `after: error` hook. The `after: action hook`
+runs immediately after the create action fails for a particular repository—so
+before any subsequent actions for that repository or other repositories even
+have a chance to run. Whereas the `after: error` hook doesn't run until all
