Yes, you can. It really does equivaltent of:
if expr $query_string : '.*\.listing$'; then
ls ${query_string%.listing}
else
cat ${query_string}
fi
but it's in C, so it is faster and more secure.

Yes, you can mod_rewrie. IIRC mod_rewrite just creates a new URI with
which the whole processing is restarted as if it was the one originaly
provided. So the script won't know.
However, it would be more interesting to AddHandler and/or SetHandler.
It would mean to change the logic to look in PATH_INFO first and only if
it's not defined to look in QUERY_STRING. That would allow you to say:
<LocationMatch "http://uri-to-archives/.*/.listing">
SetHandler arch.cgi
</LocationMatch>
I am not sure how this would deal with /../, perhaps it has to be fixed
in the regexp. But it would save the CGI execution overhead for files.
It's not as simple as I wrote above, though. I'd have to look in the
apache manual how exactly it works and find out what exactly the CGI
gets. With that information it should be easy to enhance it to be
useable either way (the environment is different in each case so it
simple to distinguish).
