 Why does it do that? We're passing a specific file name to it.

In the case of `vc-root-diff` at least, it'= s passing in a directory; the command is essentially `hg status -A ./`, and= the CWD is indeed the repo root.=C2=A0 I did this by running `vc-root-diff= ` from a dired buffer visiting the repo root.

Hofstadter's Law:
= =C2=A0 =C2=A0 It always takes longer than you expect, even
=C2=A0 =C2=A0= when you take into account Hofstadter's Law.
