policy for commiting api docs

[Unknown <ensonic hora-obscura de>]

hi,

I noticed that the 
* GtkBinding modules is undocumented
* signals for the GtkTreeView are undocumented

I volunteer to work on this (grepping though the changelogs of the file
and asking here). Docs are important - it's quite unfair of the ones who
originally wrote the code to leave out the docs.

Now I'd like to know, if I may commit doc additions right away or if I
should better send a patch to bugzilla and/or this list for review.

Ciao
  Stefan
