[Usability]HIG should advise against Yes/No in confirmation alerts

[John Levon <levon movementarian org>]

The HIG draft

http://developer.gnome.org/projects/gup/hig/draft_hig/windows.html#alert-windows

does not seem to contain any text advising against the use of
context-dependent "Yes" / "No" labels in confirmation alerts (although
the examples avoid them).

Shouldn't there be some text advising of this here ?
