commit e303cb18077538b5ec32e73ce8def958d40c361f

    Fix indexing of module functions that return complex types.
    
    Return types that consist of more than one word need to be enclosed in
    braces, see Info node `(texinfo) Typed Functions'.  Otherwise they are
    indexed incorrectly.
    
    * doc/lispref/internals.texi (Module Values): Enclose multi-word
    return types in braces.
