It was already in the process of being changed, hence the first seven 
lines of the function.  That lapply is no longer needed and has been 
removed (but was not yet committed).

We do normally ask that problems with R-devel ('Under development 
(unstable)') not be sent to R-bugs: as is quite often the case this is 
something that is under active development.
