    gmmproc: Small improvement of enum documentation
    
    * tools/pm/DocsParser.pm: Some small improvements of
    lookup_enum_documentation(). E.g. '\n' is replace by ' ' instead of removed,
    and G_NORMALIZE_DEFAULT is converted to NORMALIZE_DEFAULT instead of
    Normalize::DEFAULT. But still not perfect.
