org-html.el: correct HTML export of dedicated target.

* org-html.el (org-format-org-table-html): fix anchors in HTML
export (thanks to <aankhen@gmail.com>)
(org-html-protect): fix a  bug that prevents some target to be
rendered correctly.

* org-exp.el (org-solidify-link-text): a single "-" to avoid a
"&ndash" rewrite in HTML export later.
