[O] Bug: unconverted dashes in HTML export

[Thomas Morgan]

Dear Org mode hackers,

I started Emacs with `emacs -Q -l setup.el test-case.org', then typed
`C-c C-e h o' to export to HTML and open the result.  The setup file
(`setup.el'), test case (`test-case.org'), HTML output (`lose.html'),
and a PDF printed by the web browser (`lose.pdf'), are attached.

The test case contains a one-cell table with three hyphens (`---').
I expected this to be converted to an em-dash in the HTML output,
but it remained three hyphens.

A patch fixing the problem is attached, along with the HTML and PDF
produced after the patch was applied (`win.html', `win.pdf').

I started preparing this report last May (sorry for the delay)
but just confirmed the bug again with Org-mode version 8.2.5g
(`release_8.2.5g-663-g24a213' @ `/src/org-mode/lisp/') and GNU Emacs
24.3.1 (`x86_64-unknown-linux-gnu', X toolkit, Xaw3d scroll bars)
of 2013-09-24.

Thanks and best regards,
Thomas
