That's very weird.  I can confirm this behavior on xemacs with the 
5.3.2.  Also, another thing related to the original post, if I do \C-c 
\C-l like David suggested, the commands are never echoed to the *R* 
buffer, nor the output!  You just stare at it until a new > appears and 
all of the good stuff went to the big bit-bucket up in the sky.  Who 
wants that?  I must be missing something very fundamental here.
