Thanks.

| But I still do not understand this:
| 
|        chunk=`echo -n $arg`
| 
| thing (despite later messages). 

It is trying to turn $arg that might be splitted into many strings
(because of over quoting -- despite the popular belief that quoting
should be done systematically) into a single string so that is has
only one quote at the beginning and one quote at the end.

| 
|        chunk=$arg
| 
| and it works (the problem was on test line).  Zsh manual claims
| that word splitting is not done on assignment (and I think
| same is true for bash).

That behaviour is controlled by options, so the simpler asssignment
which should work is brittle.  You can remove the echo, but PLEASE
don't quote $arg in the assinment.
