tramp (2.1.16-pre); Needless remote access?

[David Abrahams]

I'm not sure how this could have happened, but I just found TRAMP
initiating remote acesses when I was staging/un-staging files in magit
on a *local* git repository.  I did (setq default-directory "~") in the
magit buffer to try to stop it, to no avail.

Unfortunately, I was also unable to get `M-x tramp-bug' to populate a
mail message ("selecting deleted buffer") until after I had destroyed
probably-valuable information by doing tramp-cleanup-all-connections and
tramp-cleanup-all-buffers, so what you see below doesn't reflect very
much about the state of things at the time I had the problem.

I also have been unable to force the problem to be reproduced so far.
