bug#70418: ls bug

[Toby Kelsey]

There appears to be a bug with 'ls' when using the '-f' and '-l' options, or at least an inconsistency with the man 
page. The man page says '-f' list entries in directory order and does not mention any incompatibilities with other 
options, however I find using it with the '-l' option gives different ouputs depending on the order of options. See the 
following script log for an example:


toby@toby-pc:/tmp$ mkdir test
toby@toby-pc:/tmp$ cd test
toby@toby-pc:/tmp/test$ touch c b a foo bar
toby@toby-pc:/tmp/test$ ls -lf
.  ..  c  b  a  foo  bar
toby@toby-pc:/tmp/test$ ls -fl
