But logically, if buildout picks versions and puts them in a version 
file, then they are still picked during the current buildout run, so 
when allow-picked-versions is false, buildout should quit, independent 
of the update-versions-file setting.

I guess I actually simply would not use this particular combination of 
settings.  If I want buildout to quit with an error when a version is 
picked, I should just use false for both settings.

So: no big deal.
