It seems to be deliberate. calc-dispatch uses (sit-for
echo-keystrokes) to wait for further input, then acts differently
depending on what keys were pressed or if the sit-for timed out starts
calc normally. Repeating the keys that invoked calc-dispatch seems to
try to evaluate the current line using calc as far as I can tell.
