Actually, it's due to propagating the exit status in the wrong format.
strace demonstrates:
waitpid(-1, foobar: nothing appropriate.
[{WIFEXITED(s) && WEXITSTATUS(s) == 16}], 0) = 24037
--- SIGCHLD (Child exited) @ 0 (0) ---
sigreturn() = ? (mask now [])
waitpid(-1, 0xbfbd28b8, WNOHANG) = -1 ECHILD (No child processes)
rt_sigaction(SIGINT, {0x805a0f0, [], 0}, NULL, 8) = 0
rt_sigaction(SIGQUIT, {SIG_DFL}, NULL, 8) = 0
exit_group(4096) = ?
man needs to turn the wait status returned by waitpid into something
suitable for passing to exit. I've done this upstream:

* lib/pipeline.c (pipeline_wait): Mangle return value into a value
suitable for passing to exit (Debian bug #477305).
