Why does it set to an empty string? It shouldn't, at least with GNU
CoreUtils 5.97:
lucasvr at Ummagumma ~]mkdir foo
lucasvr at Ummagumma ~]readlink -f foo
/Users/lucasvr/foo

GNU CoreUtils shows an empty string when one skips -f flag, though:
lucasvr at Ummagumma ~]readlink foo
lucasvr at Ummagumma ~]

Probably to take its full path, as seen in my version of readlink -f.

I'm taking a look there..
