+  Specifying Multiple Revisions
+  
+      When Mercurial accepts more than one revision, they may be specified
+      individually, or provided as a topologically continuous range, separated
+      by the ":" character.
+  
+      The syntax of range notation is [BEGIN]:[END], where BEGIN and END are
+      revision identifiers. Both BEGIN and END are optional. If BEGIN is not
+      specified, it defaults to revision number 0. If END is not specified, it
+      defaults to the tip. The range ":" thus means "all revisions".
+  
+      If BEGIN is greater than END, revisions are treated in reverse order.
+  
+      A range acts as a closed interval. This means that a range of 3:5 gives 3,
+      4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
+
