Subject: patch 9.1.0512: Mode message for spell completion doesn't match
 allowed keys

Problem:  Mode message for spell completion doesn't match allowed keys
          (Kyle Kovacs)
Solution: Show "^S" instead of "s".
          (zeertzjq)

This matches the code in vim_is_ctrl_x_key():

	case CTRL_X_SPELL:
	    return (c == Ctrl_S || c == Ctrl_P || c == Ctrl_N);

fixes: neovim/neovim#29431
closes: #15065
