Bad links on Documentation page

[Zbyszek Skowron <zbychs gmail com>]

Hi,

On your documentation page
(http://www.gtkmm.org/en/documentation.html) the links are not working
properly.
For example links starting with "http://help.gnome.org/devel"; open as
"http://help.gnome.orgdevel"; - even though a proper address is
displayed in the browser status bar when hovering over a link.

(Win7 64, Firefox 18.0.1)
