描述

I would expect mosh --local 127.0.0.1 "sh -c 'exit 42'" ; echo $? to exit with code 42 as does ssh, but it exits with 0. Is this behavior intentional?

研究方向
Investigate how mosh propagates the exit code from the remote command back to the local shell. Look at the client and server code in the mosh repository, especially the terminal handling and session management. Check if the exit code is being intentionally dropped or if it's a missing feature. Compare with ssh's behavior to understand the expected implementation.
