[issue9246] os.getcwd() hardcodes max path len

>From a practicality point of view, we need to make no change at all:
nobody sane ever has a current working directory path of more than
1000 characters. Even if people have very long path names, they
don't make them the current working directory.

So if anything is changed, it's for purity only. Then, for purity,
we should get it right and support any path that the operating system
supports.
