+\r
+A little bit of both I guess; not too bad.\r
+\r
+An alternative might be to make the variant without the trailing /\r
+recursive, so folder:foo would match all files in all subdirectories\r
+under foo, including foo/new and foo/cur. This would be more compatible\r
+with the current folder: prefix too.\r
+\r
+Then, if you wanted to match without recursion, you'd have to have\r
+"folder:foo/. OR folder:foo/new OR folder:foo/cur" assuming new and cur\r
+are leaf nodes, and if not, with "/." at the end.\r
+\r
+But you'd have to decide what to do with "folder:foo/" which would then\r
+match nothing.\r
+\r
+There's definitely room for thoughts and discussion.\r
