Ok, you win.  Next time I get scare, I should ask you first. :)

In a single picture, links currently look like this:

Symlink		can point to inodes or cowlinks or hardlinks
Hardlink	can point to inodes or cowlinks
Cowlink		can point to inodes

I like it.

Not sure about the current count, but it looks like most people favor
the indirect approach now.
