I don't think it's possible to change that behaviour without patching
CGit.  Given how URLs are constructed, it looks a bit complicated to fix
in all cases, but you could remove the setting of "virtual_root" in
cmd_main() to force using query parameters instead of virtual paths in
URLs.

Can you tell where the 404 is generated?  Is this a case of httpd
returning an error when it shouldn't, or is it a behaviour difference
that CGit isn't handling correctly - maybe other CGI hosts strip
trailing slashes before passing a path to CGit but httpd doesn't?
