Options -c and -n implemented by #85

Describe the bug
Pwd is getting physical path instead of logical with --logical parameter

To Reproduce
Steps to reproduce the behavior:

1. Run pwd with --logical
2. See error

Expected behavior
For example: Assume that /bin is a link to /usr/bin:
One should get /bin if --logical parameter is specified, /usr/bin otherwise

Additional context
May be a problem with getgrouplist function on libc crate

We lack examples in the documentation of methods and structures, and also a better module level documentation

Unresolved questions:

All extension options/flags required are only there because most implementations also do. But there is just another two extensions left for all major versions of the utility, -A, -B and -f. Should those last three be implemented as well?

History

-n, -b, -E and -s implemented by #106

When a NAME is passed as argument, the output is wrong

How to reproduce

./groups root

Is your feature request related to a problem? Please describe.

Describe the solution you'd like
Use https://doc.rust-lang.org/std/ffi/struct.CString.html#method.new

It will reduce your code because you will no longer have to construct a Rust string with a \0:

        let string_name = {
            let mut s = name.to_string();
            s.push('\0');
            s
        };

It's already done inside CString::new
