[Dev-luatex] scantokens in LuaTeX (issue 733)

Hello, LuaTeX's \scantokens behave differently than eTeX's, as mentionned in [issue 733 in the bug tracker](http://tracker.luatex.org/view.php?id=733). The issue 733 does not explicitly say what goes wrong, so I though I'd provide a shorter example of the problem: pdftex '\newlinechar10 \scantokens{\show^^JX}Y' shows "the letter X", while using luatex I get "the letter Y". What happens is that LuaTeX's \scantokens only reads the first line of the pseudo file written by \scantokens. Regards, Bruno PS: I tried directly commenting on issue 733 but couldn't find how, please let me know if this mailing list is not the correct place.
