In Debian testing/unstable, they seem to be going through adding .conf 
to the end of all files in /etc subdirectories that have the behavior of 
loading all files in the directory, presumably to solve the problem of 
backup files being evaluated in those directories.  Quite a few of these 
are shell scripts, but having looked properly now, I can only find one 
out of around 300 .conf files under /etc that starts with #!.
