Let me post the umpteenth patch for /bin/ls compatibility for
publicfile. I feel that this one has the following advantages:
- it does not use stdio (sprintf, snprintf) that publicfile so carefully
avoids; it only uses the DJB substdio functions.
- avoids the use of bounded arrays (char [xx];)
- it tries to mimic the EPLF implementation in the amount of information
that is put out (for example: non-regular files or unreadable files will
have rights '----------' and size 0)

Tested succesfully with Netscape, IE, and the OpenBSD ftp client.

It does not work with ncftp. (ncftp does not really issue 'cd' commands
to the ftp-server. It caches this information to issue commands with the
cached path as an argument). I have seen patches on this mailinglist
that address this issue as well, but I feel it's not publicfile's
problem.
