Bug 15580

ftp(1) file completion does not work if server is wu-ftpd 2.6.0. This is due to nlist (NLST) change in wu-ftpd 2.6.0. 
You can see also docs/15408 (ls = dir != nlist).

Fix: 

When doing remote globing do a NLST "-a xxxx" (file util.c).
Here is a patch obtained with "diff -c util.c.old util.c > util.c.patch" from -current ftp/util.c ($FreeBSD: src/usr.bin/ftp/util.c,v 1.8 1999/08/28 01:01:35 peter Exp)
