+tests with empty value
+----------------------
+
+Fully empty revset
+
+  $ fileset "status('', '4', added())"
+  hg: parse error: first argument to status must be a revision
+  [255]
+  $ fileset "status('2', '', added())"
+  hg: parse error: second argument to status must be a revision
+  [255]

+Empty revset will error at the revset layer

+  [255]
+  $ fileset "status('2', ' ', added())"
