Nit:
With the patch, the code in PR #92929 now issues 
```
> a.out
 No error!
cat: no: No such file or directory
 exitstat= 1
 cmdstat= 3
 Invalid command line
 ```
 
 Both `exitstat` and `cmdstat` are correct now, but the error message `Invalid command line` seems not quite accurate. 
 For instance, if I changed the command to a random `fakecommand`, it will give the same message.
