Default the repository path to the current directory for all variants.

Trivial fix, most of this is documentation patches.

Correctly use self.DEFAULT_USERNAME as a default for --username.

Before this, it was being shown as default, but failing to specify the
--username on the cvs2git command line was nevertheless a fatal error.
This fix should ensure correct defaulting for cvs2git, cvs2bzr, and
cvs2hg.
