Support for a base URL

[larsvilhuber]

In converting Mediawiki XML to Markdown(_github), I want to subsequently host the files directly on a Github wiki. The links between pages do not support this (or I have not discovered an option to use).

I converted using php convert.php --filename=dump.xml --indexes=true.

The resulting links are like this; [VirtualRDC hardware](/VRDC:nodes "wikilink"), which, when hosted as a Github wiki, link to http://github.com/VRDC:nodes.

The following two alternatives work:

• [[VirtualRDC hardware|VRDC:nodes]]
• [VirtualRDC hardware](./VRDC:nodes "wikilink") (note the dot in front of the slash VRDC)

Any chance this can be added as an option?
