updating bugzilla cases

[Stefan Kost <ensonic hora-obscura de>]

hi damon,

I went over the open cases for gtk-doc and commented where appropriate.
I don't have sufficient rights to close bugs. So heres a list:

bug that ihmo can be closed (invalid/not-a-bug):
http://bugzilla.gnome.org/show_bug.cgi?id=133500
http://bugzilla.gnome.org/show_bug.cgi?id=166462

bugs the need review
http://bugzilla.gnome.org/show_bug.cgi?id=167688
  sounds useful to me
http://bugzilla.gnome.org/show_bug.cgi?id=312504
  is easy to do, but I am unsure if we want it
http://bugzilla.gnome.org/show_bug.cgi?id=303337
  looks good to me
http://bugzilla.gnome.org/show_bug.cgi?id=90602
  sounds like something we want too, I just guess the original offer
hold no longer :(
http://bugzilla.gnome.org/show_bug.cgi?id=156643
  can IMHO be applied (see comment)

Ciao
  Stefan
