Currently I narrow down problem with symlinks emulation on win32
to 3 important functions:
os.symlink, os.readlink and os.lstat.

Does bzr really use follow-symlink approach or only readlink?
There is some tests in test_osutils those expect os.path.realpath
to follow symlinks. Are there any other features I need to emulate
for bzr? Probably os.stat should follow symlink too?

Another question: how follow-symlink approach works in Linux
if symlink point to another symlink? Or Linux effectively prevents this?
