I think I've found an issue when head is called with -n-0 parameter
It should return whole file but only seem to work for files with newline
character at the end.

I'm not observing this problem on Ubuntu 14.10 x86-64; see below.  Which platform and version of 'head' are you running?  Can you send a recipe to reproduce the bug?

$ printf 'abc\ndef\nghi' >t
$ head -n-0 t
abc
def
ghi$ head --version | head -n1
