In my case, the problem is that I *am* using an alias. The background
is that MoinMoin includes mod_python support now. However, MoinMoin
URLs are of the form

    http://server.name/wiki/PageName

Here, "wiki" is an alias set up to point to the MoinMoin instance
directory, and PageName is the name of the page to display. In order
for the MoinMoin code to figure out the page, it needs to be able to
split the URL up into the "script" (/wiki) and the "path" (/PageName).
I suspect that this is because the original version of MoinMoin used
CGI, so the "script" was /whatever/path/you/want/moin.cgi and the path
can come from the standard CGI PATH_INFO variable.

Actually, I think I have a solution. Rather than using a Directory, I
can just use a Location. If I do that, the path_info attribute is
"correct" (ie, it includes everything after the part of the URL which
names the location).

So I have

<Location /wiki>
    # Use mod_python as handler
    SetHandler python-program

    # set the path to the MoinMoin package and to the moin_config.py
    PythonPath "['D:/Moin/dbawiki']+sys.path"

    # choose the ModPy Request class as handler
    PythonHandler MoinMoin.request::RequestModPy.run
</Location>

This seems to work as required. (I'm not 100% sure why, as MoinMoin
seems to be using SCRIPT_PATH, which is empty, but hey, if it works...
