* doc/automake.texi (@copying): Do not repeat the version.
(Top): Use @insertcopying. Add a @detailmenu, this works around
Emacs 21's inability to lookup indices in sub-nodes (reported
by Kevin Ryde).
(C++ Support, Assembly Support, Fortran 77 Support, Java Support,
Support for Other Languages, Preprocessing Fortran 77, Compiling
Fortran 77 Files, Mixing Fortran 77 With C and C++, How the Linker
is Chosen): Add missing descriptions in menus.
(Fortran 77 and Autoconf): Remove, this node was just saying "use
Autoconf 2.53 or greater".
