So that such output processing may be done efficiently, there is a new
variable, comint-last-output-start, that records the position of the start of
-the lastest output inserted into the buffer (effectively the previous value
+the last output inserted into the buffer (effectively the previous value
of process-mark). Output processing functions should process the text
between comint-last-output-start (or perhaps the beginning of the line that
the position lies on) and process-mark.
1. This copies the text from the right-hand buffer as a second column
in the other buffer. To go back to two-column editing, use C-x 6 s.
-Use C-x 6 d to disassociate the two buffers, leaving each as it
+Use C-x 6 d to dissociate the two buffers, leaving each as it
stands. (If the other buffer, the one that was not current when you
type C-x 6 d, is empty, C-x 6 d kills it.)
