[O] Bug: HTML Export doesn't handle internal link with spaces [8.0.7 (8.0.7-6-g13cb28-elpa @ /home/jbalint/.emacs.d/elpa/org-20130812/)]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

------------------------------------------------------------------------

I've generated a link to a headline with `org-store-link' and
`org-insert-link'. It's rendered into the Org file like so:

  [[*Headline%20with%Spaces][Headline with Spaces]]

The HTML export renders this as an italic string (the last cond in the 
org-html-link function).

The HTML exporter gets a "fuzzy" link which is handled in this block:

     ;; Links pointing to a headline: Find destination and build
     ;; appropriate referencing command.
     ((member type '("custom-id" "fuzzy" "id"))
      (let ((destination (if (string= type "fuzzy")
                             (org-export-resolve-fuzzy-link link info)
                           (org-export-resolve-id-link link info))))

The problem is in `org-export-resolve-fuzzy-link' which get's the path
directly from the link:

  (let* ((raw-path (org-element-property :path link))

But at this point it has "%20" in it which causes a problem when
splitting it:

     ;; Split PATH at white spaces so matches are space
     ;; insensitive.
     (path (org-split-string
        (if match-title-p (substring raw-path 1) raw-path)))

This does nothing because there are no spaces in the string (they are
%20 here). The search for a headline matching this fails. I can solve
this here by doing:

         ;; Split PATH at white spaces so matches are space
         ;; insensitive.
         (path (org-split-string
                        (replace-regexp-in-string "%20" " "
                (if match-title-p (substring raw-path 1) raw-path))))

I'm not it's the proper solution though. Thanks.
