makeinfo --html creates dangling #dir refs

[Ralf Wildenhues]

Hello Karl, bug-texinfo readers,

In PR automake/531 [1], Michael Ploujnikov reports about broken links in
the HTML version of the Automake manual, generated by 'makeinfo --html'.
Most of the links are some outdated symlinks, substitutions, a couple of
renamed nodes, all fixable within Automake.

There is one set of errors that is IMHO due to makeinfo, though: it
creates references to #dir, but there is never an anchor to resolve
this.  The same issue exists with gendocs.sh generated pages.

For example:

<a name="Top"></a>
Next:&nbsp;<a rel="next" accesskey="n" href="#Introduction">Introduction</a>,
Up:&nbsp;<a rel="up" accesskey="u" href="#dir">(dir)</a>

Can this be fixed within texinfo, either with makeinfo or gendocs.sh?

I suppose a related issue is that the upload of gendocs.sh products
still requires adding some entries to manual/.symlinks in order for
links to other packages' manuals to more or less work.  Fixing this
so that it blends right in with www.gnu.org hierarchy would be neat.

Thanks,
Ralf
