3.1: bug in --stats

[Carlos Carvalho]

3.1, including the latest version, produces bogus ---stats output:

% rsync -r --stats . > /tmp/3.1-n
% tail -n 17 /tmp/3.1-n

Number of files: 3,159 (reg: 2,984, dir: 173, link: 2)

3.0.6 gets it right:

Number of files: 3159
Number of files transferred: 0
Total file size: 327945064379 bytes
Total transferred file size: 0 bytes
Literal data: 0 bytes
Matched data: 0 bytes

Total bytes sent: 69219
Total bytes received: 184

sent 69219 bytes  received 184 bytes  138806.00 bytes/sec
total size is 327945064379  speedup is 4725228.94

BTW, why aren't these fields

struct stats {
    int64 total_size;
    int64 total_transferred_size;
    int64 total_written;
    int64 total_read;
    int64 literal_data;
    int64 matched_data;

of type size_t?
