Subject: 25.3; Wrong value for comint-process-echoes will cause
 comint-send-input to hang
Date: Tue, 9 Jan 2018 22:16:15 -0800

If comint-process-echoes is set to t and the subprocess does not echo
input (e.g., Bash depending on configuration), comint-send-input (RET)
will hang on a long-running process that does not write output.

comint should remove the echoed input line asynchronously.
