Comment:
ok! last nit I think: the commit message should mention we are still using `gtk-doc`, but we are going to move to `gi-docgen` (assuming that's the plan), and there should be a comment in this line explaining what the deal is. Also it should look like:

`#vmove ....` instead of `#     vmove`
