Now, we have to write wrapper if we need to pass more than one argument
to the interpreter.

For example, now we can't write something like

#!/usr/bin/env python -c

in shebang. It will be interpreted as /usr/bin/env "python -c" and we will
get ENOENT.

With the patch it will be interpreted according to shell syntax.
