[Vala] Extra documentation for vapis on Valadoc

[Steven Oliver <oliver steven gmail com>]

I was looking through Valadoc.org today and came across this entry:

http://valadoc.org/#!api=glib-2.0/GLib.Markup.printf_escaped

My question is how did the extra documentation get there? I looked in the
Glib-2.0 vapi but there's nothing extra there.
