I don't think we need auto_execok here, as osascript is available on
every Mac system. We might even specify the exact path, it's always
/usr/bin/osascript. Is that preferable?

I agree that "catch" might be a good idea though. It raises two
questions though:

1) Should we make the same change in gitk then? It already has the same
   code without the catch (released in 1.8.3 already, btw).

2) Should we think about some way of sharing code between gitk and
   git gui, so that these kinds of changes don't have to be made twice?
