Can't wrap my head around it, calling for help.

So I have a /tmp/script:

```
#!/bin/execlineb -S0
if { redirfd -w 1 /tmp/runme s6-echo $_at_ }
execlineb /tmp/runme
```

Which I call like this:
```
/tmp/script strace -etrace=execve s6-echo A "B C"
```

And it produces incorrect result (3 args are passed, not 2).

How /tmp/script can be modified so it handles non-trivial case correctly?


Shell version of behaviour I am looking for (probably not portable,
but nevertheless):

```
#!/bin/sh
printf "%q " "$_at_" >/tmp/runme
exec /bin/sh /tmp/runme
```
