With an alias for "cd" as "pushd"...

-------------------------------
#!/bin/sh
alias cd=pushd
(cd test; ls) | while read file
do
echo -- $file --
done
-------------------------------

$ ./changedir
-- /tmp/test /tmp --
-- 1 --

Not exactly the same, but close... Probably better not to have your "cd"
grouped with the "ls" anyway.  Still, can't reproduce your output...

   ...
   PREVIOUS=$(pwd)
   cd test
   for i in $(ls -1); do
     echo "-- $i --"
   done
   cd "$PREVIOUS"
   ...

Or you could use pushd/popd (but they're bashism's, as is "read"
apparently...).
