Here is a comparison matrix which shows a case in which
|
|
it is possible for the forward and backward scan in 'diag'
|
|
to meet along a nonzero length of diagonal simultaneous
|
|
(so that bdiag[d] and fdiag[d] are not equal)
|
|
even though there is no snake on that diagonal at the meeting point.
