Fixed a typo that broke automatic youtube video support in addurl.


Now there's an easy way to get an overview of how close your repository is to meeting the configured numcopies settings (or when it exceeds them).

# time git annex status . 
[...]
numcopies stats: 
    numcopies +0: 6686
    numcopies +1: 3793
    numcopies +3: 3156
    numcopies +2: 2743
    numcopies -1: 1242
    numcopies -4: 1098
    numcopies -3: 1009
    numcopies +4: 372

This does make git annex status slow when run on a large directory tree, so --fast disables that.
