The second line comes from handle_alias itself. It calls
die_errno whenever run_command returns a negative value.
However, only -1 indicates a syscall error where errno has
something useful (note that it says the useless "success"
above). Instead, we treat negative returns from run_command
(except for -1) as a normal code to be passed to exit.

Why does this make a difference? We only ever return -1, zero, or a
positive value from run_command/finish_command/wait_or_whine, as far as
I can see.
exit(ret);
