[Rd] data.frame() args in transform()

Starting in SVN revision 47035 (which shows up in the R-2-9-0 line), transform.data.frame() started accepting arguments like 'row.names' and 'stringsAsFactors' to be passed through to the data.frame() function. It looks like this was an unintentional side-effect of letting multiple columns be added properly.

Given that this has been implemented for quite a while, should it now be documented? It's a little strange to support it though - the 'stringsAsFactors' argument might be handy, but 'check.names', 'row.names', and 'check.rows' are perhaps questionable. If it's desirable to document the behavior, here's a possible patch.
