Ok, will do this.

Subject: Do not check if getcwd() result begins with a slash
It's just me being too kernel-oriented - inside the kernel, a d_path()
return value pathname can be either a real path, or something like
"pipe:[8003]", and the difference is the '/' at the beginning.
In user space, and for getcwd(), the check doesn't make sense. So please
just remove it, and sorry for my idiotic "I've worked with the kernel for
too damn long" programming mistakes.
