[Orgmode] HTML export and absolute file names

[Ulf Stegemann]

With commit 330fb540 export of file links to HTML in
`org-html-make-link' changed insofar that file links with absolute paths
are now prepended with `file://'.  This seems to make it virtually
impossible to create HTML code like `<a href="/abs/path.html">'.

However, creating HTML links with an absolute path (and without host
name) is often desirable, especially when publishing to a site (where
`file://' links are rather seldom needed).

Would it be reasonable to address this and what would be the best way of
doing so (new export var, new link type ...)?
