lynx-dev make install-help bug

[Bela Lubkin]

When you `make install-help`, it runs:

        echo Appending interim-fix for existing html files
        sed     -e '/^#/d' -e '/[:@]/d' -e '/^$/d' \
                -e 's%\(.*\)=\(.*\.html\)$%s=\2=\2=%g' \
                ./lynx_help/help_files.txt >> \
                /local/lib/lynx/lynx_help/help_files.sed

which results in a bunch of expressions like:

  s=lynx-dev.html=lynx-dev.html=

When applied to about-lynx.html, this produces the following changes:

  11c11
  < <A HREF="http://www.flora.org/lynx-dev/html/";>Lynx-Dev Archives</A> ]
  ---
  > <A HREF="http://www.flora.org/lynx-dev.html/";>Lynx-Dev Archives</A> ]

  < HREF="http://www.flora.org/lynx-dev/html/";>archives</A> in html
  ---
  > HREF="http://www.flora.org/lynx-dev.html/";>archives</A> in html

Bad.  Same in lynx_dev.html.  The left-hand side of the sed expression
needs to have its "."'s quoted (converted to "\."'s).

Actually, I don't understand what this is trying to accomplish at all.
But it's certainly corrupting some of the links in my help files.
