To understand that, you need to know how github "fork of" works.
I have no idea either, but here is my guess:
Github decides which repo forked of by section '[remote "origin"]'
in file .git/config.
Generally, if you "git clone git://git-repo", the origin is recorded
into this section. However, not all repos have the section. For example:
$ mkdir repo_a
$ git init
$ cd ../repo_b
$ git push ../repo_a master
In this case, repo_a/.git/config has no '[remote "origin"]' section.
Without this section, github has no idea where this repo forked of,
and consequently, the "fork of" link is not shown.
