Re: void Gtk::Widget::get_preferred_width pass nullptr

[Daniel Boles <dboles src gmail com>]

fwiw, of course, where you see this for std::string or Glib::ustring parameters, the empty string "" should usually suffice

I mention it because that's a pattern I think is much less subjective and therefore more reasonable for the doc processor to substitute, and I suggested that here: https://bugzilla.gnome.org/show_bug.cgi?id=785899

The problem with "blah blah, or NULL" is that it could be written in various slightly different ways, which would complicate detecting and removing it.

Maybe one day I'll learn enough to try it out just for a laugh, though. :D
