spawn: doesn't appear as though file descriptors are inherited

[da-x]

I tried a long running command, e.g:

spawn!(docker build -f ${tmp_docker_file} -t ${tag} ${tmp_path_sub})?.wait_cmd_result()?;

But output blocked until the command finished execution successfully.
Parent command executed in a terminal.

Consistently, I don't see Stdio::inherit() being used the code of rust_cmd_lib.

The alternative to use the standard API worked for me:

use std::process::{Stdio, Command};   
let mut cmd = Command::new("docker"); 
cmd.stdout(Stdio::inherit());         
cmd.stderr(Stdio::inherit());         
cmd.stdin(Stdio::inherit());          
cmd.arg("build");                     
cmd.arg("-f");                        
cmd.arg(tmp_docker_file);             
cmd.arg("-t");                        
cmd.arg(tag);                         
cmd.arg(tmp_path_sub);                
let mut child = cmd.spawn()?;         
child.wait()?;

Thanks for reporting this, just fixed in the last commit.

BTW, Stdio::inherit() is the default setting, so we don't need to call it explicitly. I would also just use run_cmd!() for your above example.

Thanks! I reviewed the changes and added a few comments.
