                       R \"U N L I S T
                       
     LNS has this special scheme of collecting commands in R\"unbuffers
     (see buffer.h) and execute them from a stack. The R\"unbuffers are
     implemented in buffer.*. This implements the stack.
     
     BEWARE: The R\"unList code does not delete R\"unbuffers!
