what should be cleaned using flag -f?

[Peter Johansson]

as now the target directory (svnstat_output) is removed. Perhaps it makes more sense to only remove target/root, which means target may then contain the svnstat output from many different projects and when enforcing/over-writing we are not removing everything, but only the root in question.

This change generates many issues e.g. it must be checked whether target exists (otherwise create it). Also what happens must be clearly documented (also in cmd help)

[Jari Häkkinen]

The project specific sub-directory should be removed.

[Peter Johansson]

(In [104]) closes #39 checks that target and root exist, default parameter is changed to ., there is no longer a creation of a target directory, program burps if root directory already exists in the target directory.
