ignoring 00-suffixed plains when using --keep-guessing?

[royce]

When using --keep-guessing, what's the best way to ignore 00-suffixed plains?

a61915a2d80ae6a1:Lü           <--------- this is the same as $HEX[4cc3bc]
a61915a2d80ae6a1:$HEX[4cc3bc00]
a61915a2d80ae6a1:$HEX[4cc3bc0000]
a61915a2d80ae6a1:$HEX[4cc3bc000000]
a61915a2d80ae6a1:$HEX[4cc3bc00000000]

I can script something, but it's a little unwieldy.

Is it worth opening a feature request for?
