> The new mode line right alignment requires setting `mode-line-format` to
> a list that contains (as in `memq`) the symbol
> `mode-line-format-right-align`.  This is a bit brittle, and currently
> `eldoc-minibuffer-message` modifies `mode-line-format` in a way that
> happens to break `mode-line-format-right-align`.  To see that, set
> `mode-line-format` to '("" mode-line-format-right-align "foo bar") and
> then type `M-: (list`.  Now ElDoc info appears on the mode line, but
> "bar" is no longer visible.
> 
> This patch makes ElDoc modify `mode-line-format` in an equivalent way
> that avoids messing with `mode-line-format-right-align`.

Thanks.

João, any objections or comments?
