Yes, in theory that's a good idea and it would usually work. Thanks.

Now just to make sure it doesn't get recalled as a command which
would either alter it's position in the recall buffer or would add
multiple markers in the buffer (depending on the amount of newly
entered commands in the current session). :-)

Don't forget this is the CLI which, in the 21st century, cannot even edit
wrapped command lines.

Thanks once again for the suggestion,
