Huh, never mind. After applying the patch re-compiling both files and 
restarting Emacs, the behavior now is as expected. So I pushed the 
patch, thank you.

Not sure if we should close this now.

The thing that tripped me up last time was that when 
vc-dir-revert-buffer-function is invoked, neither vc-default-dir-printer 
nor vc-git-dir-printer are called to re-print the directory entries. 
They remain as they were when the VC-Dir buffer was created (unless the 
refresh ends up adding some some files in other directories, I suppose).

While we're on the subject of buttons, I think it's odd that mouse-1 and 
mouse-2 routinely do the same thing, here and in other cases (e.g. links 
in Compilation buffers). But I suppose this is outside of scope for this 
discussion.
