# seat switch, or if there is a substantial break in service (eg here 1845-47), BUT it skips over
# periods of dissolution.

# periods of dissolution, so may not quite mesh with other days-elapsed counts).
# It explicitly filters out the "returned for two seats" cases that are not taken up but note it
# does not yet cope with ongoing (current) terms.
