bug#2944: 23.0.91; vc-dir confusing at startup

I just ran vc-dir for the first time.  It worked -- after a while.
However, at first it displayed just a few lines of info
about the overall VC handling of the directory.  It seemed
to be doing the wrong job.

So I started to wonder if that were the wrong command.
I looked at the doc string and it did not clarify the question.
It says it "shows the VC status for DIR".  The few lines
that were displayed seemed to fit that description.

Eventually the info on files did appear.  But this is a bug anyway.

I think the doc string should be fixed, and the buffer should
start out containing explanatory text such as
"The status of files is being computed
and will be displayed here when that is done."
