commit ee51a745c163f3c422a30b22f4beda0e1ead7c20
Author: Wayne Davison <wayned at samba.org>
Date:   Sat Sep 8 16:29:45 2012 -0700

    Make read_args() return the full request.
    
    When a daemon is sent multiple request args, they are now joined into a
    single return value (separated by spaces) so that the RSYNC_REQUEST
    environment variable is accurate for any "pre-xfer exec".  The values
    in RSYNC_ARG# vars are no longer truncated at the "." arg, so that all
    the request values are also listed (separately) in RSYNC_ARG#.
