Bug#241580: Can't view man:man and info:info and similar

[Jerry Haltom]

This feature has been removed upstream pending a finished rewrite of the
man->html/info->html converters. I would expect it to be returned for
the Gnome 2.8 release.

This information can be seen in the NEWS file:

Changes in 2.5.3:
-----------------
* New man converter, which will be totally unadvertised
  for the 2.6 release, due to its unreadiness
