ls --color for hard links (Ubuntu bug #123423)

[Kamil Dudka]

Hello,

at https://bugs.launchpad.net/ubuntu/+source/coreutils/+bug/123423 is proposed 
ls enhancement highlighting regular files with hardlinks (1 < nlink). I tried 
to implement this enhancement, but I have some questions:

1. Do you think, it would be useful? I think it would.

2. In the report it is proposed to highlight the number of links, but I am not 
sure with such solution.

There is already working infrastructure for file names highlighting. It will 
be much more systematic to highlight file names using this infrastructure 
than highlighting the number of links.

So I propose to add new ls color attribute to highlight files with more than 
one hardlink. What do you think?
