[NTG-context] \scantokens in luametatex

Hi, in the current luametatex upload, \scantokens (and also \scantextokens) behave odd: They seem to act like \detokenize, except that spaces get catcode other instead of catcode space: \starttext \edef\abc{\scantokens{\relax}} \abc \edef\abc{\scantextokens{\relax}} \abc \stoptext used to result in an empty output file but with luametatex, it writes \relax \relax to the output. \starttext \def\showsecond#1{\show} \edef\abc{\scantokens{a b}} \expandafter\showsecond\abc \edef\abc{\detokenize{a b}} \expandafter\showsecond\abc \stoptext prints

the character blank space
