When loading minimals with a shell script it appears that setuptex  
takes arguments from the calling shell script:

script called as "script --current" contains:
...
source ./setuptex
...

This result in the following error message:

mktexlsr: Done.
The argument "/Users/hans/TeX/context/current/tex/--current" is not a  
valid TEXROOT path.
There is no file "/Users/hans/TeX/context/current/tex/--current/texmf/ 
tex/plain/base/plain.tex"
Setting "/Users/hans/TeX/context/current/tex" as TEXROOT instead.

I guess this cannot be the intent of setuptex. It was the intention to  
just use
/Users/hans/TeX/context/current/tex/
as the TEXROOT path.
Is there a simple solution?
