Starting from emacs -Q:
Set the variable shell-command-dont-erase-buffer to a true value, say
end-last-out.
Run an asynchronous shell command: M-& echo foo RET
The buffer *Async Shell Command* appears, showing the word "foo".
Run another async command: M-& echo bar RET
The word "bar" is appended on a new line in the existing async shell
command buffer, as expected.
Change to that buffer, and cd to any remote directory:
M-x cd RET /ssh:remote: RET
Run another async command, to be executed in the remote directory:
M-& echo baz RET
Now the word "baz" entirely replaces the contents of the buffer, instead
of being appended on a new line.
