#18 [PATCH] hard links are double-counted

[Jonathan Nieder]

Hi Markus et al,

I have an enormous file:

-rw-rw-r-- 4 jrn jrn 14165272364 Jan 7 2011 svn-kde-0-1200000.xz
-rw-rw-r-- 4 jrn jrn 14165272364 Jan 7 2011 svn-kde-0:1200000.xz

As you can see, it has two filesystem entries because I am scared of
deleting one by mistake. They point to the same inode, but gdmap
draws them as separate rectangles.

I made a patch to distribute the space between the links, which I'm
attaching. Infelicities:

- when the size doesn't evenly divide the number of links, it
rounds down. Would using DIV_ROUND_UP() be better?

- there is no visual indication that a file has multiple links
and has been treated specially, so this might be confusing.
Maybe they should have a different color and show the number
of links in the status bar when it is nonzero.

Even without those refinements, I think it's an improvement.
Thoughts?

Thanks for gdmap --- I find it very useful.

Sincerely,
Jonathan
