I always thought that any program called from within a shell is called in
an own environment. here again a small test:

--- print.c ----------
#include <stdlib.h>

int main(void) {
  printf("%s\n", getenv("TEST"));
  return 0;
}
----------------------

I compiled it and replaced the `print' shell script by it, with following
result (`set1' and `set2' as before):

(null)
