The early shells (Thompson, Mashey) used "%

The Bourne shell (V7) had setable PS1 (start of command) and PS2
(continuation prompts) and set the to "$ " and "> " respectively.
Again
# was used for root
Okay, but why did Bourne switch from "%" to "$"? Was it to inform the
user
that they were using the new shell as opposed to the old one, or was there
some other reasoning behind the switch?
