suggestion: File::Listing::apache

[Slaven Rezic]

Hello,

the File::Listing documentation should probably include "dosftp" as
another option for the parse_dir function.

Attached is a script which implements an "apache" option for
parse_dir. If you like, you can include the File::Listing::apache
package into the File::Listing module.

Regards,
        Slaven
