[Rd] edit(vignette(...))

[Paul Gilbert]

I have been looking at edit(vignette(...)) in r-devel, which I think 
will be really useful for people working through vignettes. Is there a 
way to fork the editor so that the R prompt is returned? The call seems 
to be passed though to edit.file, but I don't see any simple way to get 
the prompt back until the editor is closed.  (I seem to recall there was 
a problem with the prompt returning too soon from bug.report some time ago.)

I also noticed that many (most?) packages have a vignette with the same 
name as the package. Is this considered the standard now?
