All right, I've tweaked the fix to the above bug, so that both behaviors 
work. Pushed to emacs-25. Please check and mark it as done, if 
everything works fine.

But I don't think this behavior makes a lot of sense, in general. So 
e.g. vc-print-root-log displays the log for the whole repository, but 
vc-next-action will offer you to commit the changes to the file you 
opened the log buffer from, and not the whole repository.

Same for vc-root-diff.

Indeed, it also regressed the more sensible scenario: when vc-print-log 
was called after selecting a few items in vc-dir buffer.
