cut-dirs is broken

[5hd]

As I understand it, currently the "cut-dirs" setting is broken.
Issues I encountered:

• --cut-dirs=1 together with --no-host-directories will fail to save any file
• leading / should be removed

(Sorry if you get this twice (also put as comment to your commit))

Thanks for having a look at it.
Please create a pull request (PR) - then your changes are automatically checked by our Continuous Integration (Travis CI). If that passes, I'll do a manual review.

If you have time and joy, please add a test case to reproduce a/the problem (see tests/test.*.c as examples).

Okay, I will give it a try in a few days, if I find the time.
