[tetex-doc] Warning about apache-related stuff upon upgrade

[Florent Rougon <f.rougon@free.fr>]

Hi,

I just upgraded to the latest sid, and noticed this:

,----
| Preparing to replace tetex-doc 3.0.dfsg.3-1 (using .../tetex-doc_3.0.dfsg.3-3_all.deb) ...
| Unpacking replacement tetex-doc ...
| dpkg: warning - unable to delete old directory `/etc/apache2/sites-available': Directory not empty
`----

# dpkg -S /etc/apache2/sites-available/tetex-doc
tetex-doc: /etc/apache2/sites-available/tetex-doc
#

Note that I followed the discussion about apache stuff very lightly; I'm
completely ignorant about whether this file is supposed to be here.

dpkg bug?
