Isn't the whole point of :ratchet to turn off backtracking...? From S05 (which
I know isn't official anymore but it describes what :ratchet does or was
intended to do):
"The new :r or :ratchet modifier causes this regex to not backtrack by
default."
It looks to me like the two above examples are working exactly as
designed/intended.
