raise the warning for oversized L0 to 2*target (#7985)

Browse Source 
currently we warn even by going over a single byte. even that will be
hit much more rarely once #7927 lands, but get this in earlier.

rationale for 2*checkpoint_distance: anything smaller is not really
worth a warn.

we have an global allowed_error for this warning, which still cannot be
removed nor can it be removed with #7927 because of many tests with very
small `checkpoint_distance`.
