Documentation: alphabetical order mistakes in `Appendix A @-Command List'

[Christophe Jarry]

Dear developers,

I browsed current Texinfo documentation today and found some
"alphabetical order mistakes" in `Appendix A @-Command
List' 
(http://www.gnu.org/software/texinfo/manual/texinfo/html_node/Command-List.html#Command-List):

  @equiv{}
      [...]
  @euro{}
      [...]
  @error{}
      [...]

address@hidden' entry should be located between address@hidden' and 
address@hidden'
ones.

address@hidden flag' and address@hidden' commands have the
same issue.
