Something strange is going on here:

1. when the shell output displayed in the echo area is only 1 line:

  M-! echo -e "line1" RET

then clicking on the echo area displays the *Messages* buffer correctly.

2. But when the output has more lines:

  M-! echo -e "line1\nline2" RET

then clicking on the echo area signals an error:

  mouse-minibuffer-check: Minibuffer window is not active
