I'm considering to commit the necessary changes and add the following to
NEWS [for "R-devel"]
o library(), require(), and sys.source() have a new argument
` keep.source = getOption("keep.source") '.
Hence, by default, functions from all packages (not just base)
`keep their source'.
Is this okay for everyone ?

anyone [R-core] ?
