/* Notes:
*
* I cleaned up the URL decoding and chose not to support URLs in the
* form "info:/usr/local/share/info/libc.info.gz" or similar which the
* older code attempted (and failed, maybe it had worked once) to do.
*
* The reason is that an obvious use such as viewing a info file off your
* infopath would work for the first page, but then all the links would be
* wrong. Of course, one could change kde-info2html to make it work, but I don't
* think it worthy, others are free to disagree and write the necessary code ;)
