@ymb1 The '
system' is varied, between:
../questions/X and
../q/X and
../q/X/Y and two others (one erroneously formed), see:
meta.stackexchange.com/revisions/… - why each
system has various results is the question, probably the huge mixture produces a result that some remain
bare and some are converted. Kind of an apples, oranges, grapefruit, and potato comparison. @cai
