makeinfo puts html anchors in the wrong place

[Jeffrey Yasskin]

For example, 
http://www.gnu.org/software/hello/manual/texinfo/makeinfo-options.html#index-g_t_002d_002ddisable_002dencoding-1217
links two lines below the "--disable-encoding" heading, to the top of
its definition. You should either stick the "<a
name="index-g_t_002d_002ddisable_002dencoding-1217"></a>" around the
"--disable-encoding" string, or add an
id="index-g_t_002d_002ddisable_002dencoding-1217" attribute to the
<dt> that already surrounds it.
