In the beginning of Collapse OS' Forth version, the readline sub- system was optional. This is why we had this separate RDLN$ routine and that the input buffer was allocated at boot time. It's been a while since the RDLN system has been made mandatory, but we still paid the complexity tax of this separation. Not anymore.
