@kouno Sorry but i dont tested it yet

Would this also fix Blob#data for symlinks not showing the linked file's content but the path to the linked file?

[kouno]

No, it doesn't. And as far as I know, that's how git is supposed to work. It never was intended to store the content of the file linked. I wonder if I can find a symlink on github to back this up, but here is what stackoverflow states:

http://stackoverflow.com/questions/954560/what-does-git-do-to-files-that-are-a-symbolic-link

git just stores the contents of the link (i.e. the path of the file system object that it links to) in a 'blob' just like it would for a normal file.

If it's expected behavior, it's OK. I just wasn't sure.
I think I recently came across such a case on GitHub, where also just the path to the linked file was displayed as Blob data ... but I can't remember where. :(
