> The default preParse() method  - FTPFileEntryParserImpl.preParse() - parses every entry, and removes any that do not parse.
> The entries are later parsed again to produce the main output.
> It would be more efficient to weed out null entries once after parsing.
> The preParse() method should be reserved for cases where it is strictly necessary, e.g. VMSVersioningFTPEntryParser and MVSFTPEntryParser which already override the default implementation.
