interesting that no one noticed this before ... in core-uti.tex pushing 
the line ending was messed up when changing to catcode tables (well, 
pseudo ones in mkii)

\long\def\doutilities#1#2#3#4#5% % introduceren in utility file
   {\resetutilities
    % more than one utility thing can be handled in one pass,
    % for instance lists, so we process ##1 as list
    \def\douticommand##1{\csname\s!set##1\endcsname}%
    \processcommacommand[#1]\douticommand
    \begingroup
    \def\currentutilityfilename{#2}%
    \notesenabledfalse
    \doinpututilitiestrue
    \global\utilitydonefalse
    \pushcatcodetable
    \setcatcodetable\ctxcatcodes
    \pushendofline % <<<<<<<<<<<<<<<<<<<<<<<<<
    \ifunprotectutilities % nog nodig ?
      \unprotect
    \fi

not trivial, since we then need to adapt texutil too + a bunch of 
macros; adapting mkiv may be easier

some day there will be a better interface (probably only in mkiv)
