Subject: 24.5; Line numbers disappear on empty lines if fill column indicator
 enabled and the indicator is outside the visible buffer area

[Message part 1 (text/plain, inline)]

Reproduction Guide

1. Start a graphical emacs:
$ emacs -Q

2. Open a new buffer, type some text leaving some lines blank

3. Enable linum-mode:
M-x linum-mode

4. Fetch, then load fill-column-indicator.el by:
M-x load-file

5. Enable fci-mode:
M-x fci-mode

6. Decrease the window width, so that the fill column indicator is not shown


Observed behaviour

On all the empty lines, the line numbers disappear -- except on that empty
line where your cursor might rest.


Expected behaviour

Line numbers should be shown on all lines, including empty lines
independent of the visibility of the fill column indicator.

Please bring this first to the attention of the developers of
fill-column-indicator.el.  I'm not at all sure this is a core Emacs
problem.

Thanks.
