I've refactored `org-export-as-html', factored code to build links
into `org-html-make-link'.
This does two things that I needed:
* It allows custom link types to build anchors.
* How: Call org-html-make-link. Many parameters, see the function
docstring. It returns a string containing an HTML link.
* It adds the capability to convert links when exporting.
* How: Around the export call, bind org-html-cvt-link-fn to a
function that takes 1 parameter (filename) and returns a url as a
string.
I think it also makes the code cleaner.
There are more things that could be done - it's only used by some of
the cond branches, the others are unchanged. But "publish early and
often", so here it is.
I will append the changes as a diff, since I can't push to the org
repository ("fatal: The remote end hung up unexpectedly")
