1. Summarise the issue (what were doing, what went wrong?)
Whenever I do `darcs add -r .` I get a message listing all the files in the directory that were already added, which could be a really long list.

2. What behaviour were you expecting instead?
Darcs should only attempt to add files that aren't already added, if a directory is passed to darcs add (in this example '.').

Further, if -v is passed, darcs should show the files it ignored since they were already added, i.e. something like "skipping already added file: ./foo".

3. What darcs version are you using? (Try: darcs --exact-version)
2.8.4

Example:
I have a repo with 3 files in it that have been recorded in the first revision:
_darcs  a.txt   b.txt   c.txt

I add a new file d.txt
_darcs  a.txt   b.txt   c.txt   d.txt

I do a darcs status
a ./d.txt

I do a darcs add -r .
The following files are already in the repository;
note that to ensure portability we don't allow
files that differ only in case. Use --case-ok to override this:
c.txt
b.txt
a.txt

Guillaume's recent patch will now list the fact that d.txt was added, but it would be much nicer if darcs didn't mention a.txt, b.txt, c.txt unless I specify the -v option.
