RELEASE NOTES
-------------
* The flag parsing issues of git-flow subcommands are solved for most
  platforms.

* `git flow {feature,hotfix,release} finish` now takes a `-k` flag, to keep the
  branch around after finishing.

* `git flow release finish` takes a `-n` flag, to skip tagging.

* For consistency, `git flow {release,hotfix}` now, too, have a `publish` and
  `track` subcommand, just like `feature`.

* Various minor fixes.
