Hi Hans,

Jaroslav Hajtnar (in czech TeX list) encountered the problem with \input 
primitive redefinition. He uses a macro package for comma separated 
value file (CSV) inclusion. It redefines some catcodes and \endlinechar 
before start reading such file by \input. The problem is that during 
reading CSV the reading is interrupted by reading another file like

\readfilename ->pdfr-ec
(c:/TeXLive2005/texmf-context-a/tex/context/base/pdfr-ec.tex

ConTeXt macro \input takes care about catcodes but not about 
\endlinechar so in this situation the file pdfr-ec is read with wrong 
\endlinechar which causes error.

We believe that system solution is the ConTeXt takes care about 
\endlinechar when automatically starts reading some standard files. 
Please Hans can you look at it?

Thanks
Vit

Minimal demo attached. As a result of this problem, see the '00000' in 
the lower left page corner. Actually it is character ^^X (0x18, part of 
per-cent/per-mil char) which is used as \endlinechar delimiter.
