    Handle match rules with multiple attribute values associated with a key
    
    Specifying multiple attribute strings with a given key, with the
    intention of accepting any of a specified set of values, would result in
    the last specified string overriding previous ones. Instead, delimit
    values with a :, and also allow a : in a string to be escaped with a \.
    (Another approach would have been to have libatspi allow creation of a
    match rule from a list, rather than a hash, but trying to avoid an API
    change, especially when we're in API freeze).
