anchor.diff:  Auto-generating XMLDoc
   -----------------------
   
  -This feature, originally written by Brian McNamara, auto creates xml documentation boilerplate when you type triple-slash.
  +This feature, originally written by Brian McNamara, auto creates xml documentation boilerplate when you type triple-slash, following with `<` symbol.
   
   For example, if you have the code:
   *)
  
positive.code: *)
   type SomeType() =
    
       member this.Foo(x:int, s:string) = 
           printfn "%d: %s" x s
  
  (**
  and you type `///` anywhere on the blank line before `Foo`, then you get:
  *)
  
  (*** hide ***)
  
negative.code:         printfn "%d: %s" x s
  
  (**
  Just type `///<` (the slashes and `<` simbol may be delemited by any number of whitespace symbols) on a blank line right before a member, 
  type, or module-scoped let (before any attributes, if there are any), 
  and you get a blank XMLDoc template (if there wasn't already a non-empty XMLDoc there).
