Are the origins of '1' and '4' trivially obvious to those who are
reading the test, or do these deserve comments?

We create an empty test repository, go there and create a untracked/
hierarchy with a junk file, and tell "clean" that 'untracked' is
"also" in the exclude pattern (but since there is no other exclude
pattern, that is the only one), so everything underneath untracked/
we have no reason to inspect.

So, we do not visit 'untracked' directory.  Which ones do we visit?
Is '1' coming from the top-level of the working tree '.'?  What
about the number of visited paths '4' (the trace is stored outside
this new test repository, so that's not it).

Thanks.
