As people use Sweave only sporadically, it could take years before the old usage got stamped out. And anyways, the command format is the obvious way to generate documents in scripts and makefiles, isn't it?

I use Rscript, and I expect most others do too, but I was wrong about 
how long this went unreported.  Martin Morgan reported it in February in 
R-devel and I didn't notice.  He even gave a link to it in a message in 
March on another topic; I replied to the March message, but didn't 
follow the link.

We discourage people from using bugs.r-project.org for pre-release 
issues; perhaps we shouldn't do that.
