Hi,

Here's a small problem with luatex from trunk (notice the missing 'hello' in the first line):

! \csname\endcsname. l.2 \errmessage{hello \csname\endcsname}

More generally, print_cs() screws things up when printing null_cs while selector is new_string, by indirectly calling make_string(). I think the attached patch solves the problem.

Thanks.

Manuel.

PS: Btw, I wonder about two points in tokenlist_to_cstring() - why did you comment out printing of \csname\endcsname? - why is there two times Print_uchar(e) in the definition of Print_esc?

The function was originally used from some very specific lua code only, I'll fix that. Best wishes, Taco
