Bug 6002

In the module /pine4.10/imap/src/osdep/unix/maildir.c,
This patch contains a module named maildir.c which
contains this function,

void maildir_list (MAILSTREAM *stream,char *ref, char *pat);

When "L  FOLDER LIST" is selected from the main Pine
menu, maildir_list is called with these parameters,

  maildir_list(0x0, "mail/", "%")

If you follow the code, it ends up doing a readdir()
of the directory *above* "mail/", and then does a
one-level deep recursive stat() of every file it finds.

(Try running "strace pine 2> pine.log" to see all
  the files that get stat-ed.)

On my system and probably many others, this takes a
substantial amount of time.

I'm not sure what this code is supposed to be doing.
As it stands, "ref" is never even used.  This may be
because it is called as an "abstract method" from
mail.c: mail_list(),
  (*d->list) (stream,ref,pat);

In any case, this is some weird behavior.  Its a real
problem for me because it trips the automounter when
it hits symlinks to files on remote systems that are
not always running, bringing Pine to a halt until
the stat() call times out (a minute or longer).
