And for anyone interested in doing this, I'd suggest starting with the 
code for "Paste commands only" that Tony Plate contributed to the 
Windows Rgui, which is mostly in the CleanTranscript function in

https://svn.r-project.org/R/trunk/src/gnuwin32/console.c

It would probably make some sense to move this function into src/main, 
since it's not really Windows-specific.
