Subject: 27.1; shell-command-dont-erase-buffer not honored when the existing
 shell buffer is remote
Date: Tue, 18 Aug 2020 14:50:14 -0700

[Message part 1 (text/plain, inline)]

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.
