In the previous months I have sometimes seen a very unfriendly behaviour of
mode-line. It seemed to me, that something silently disappeared from the
mode-line. So the left part of the mode-line after that action was at the
same place and the right part of the mode-line moved to the left (because
something disappeared).

Today, I have played with load-average (display-time) and finally found
it. It is load-average. When it is 0, it is removed from the mode-line. Do
you think it is good? Normal load-average is displayed as `0.80' ie. four
characters. When the load-average is zero, these four characters are
removed from the mode-line along with the preceding space so the right part
of the mode-line is moved by 5 characters. I found it distracting. When it
happened in the past, I always thought about the reason...

I think it is better to display "0.00" in that case. And maybe even better
is to use "    " (ie. spaces). I do not have strong opinion here
yet. I have to try both (which I will do soon).
