This reverts commit 19a6e24a.

This was a local experiment that I pushed to Github accidentally.

This makes it easy to download the submodule from behind a corporate
firewall.

Thanks Alexander Groß.

This has been requested by at least 10 people now, so it might be time
for one.

I thought Markdown did support URL recognition automatically.

Conflicts:
	git-flow-version

This already was the default behaviour of git-flow-feature, but now it
is the default for the other scripts, too.

RATIONALE: Due to limitations on some platforms (and some
implementations of getopt), it's impossible to turn off the -f (fetch)
option.  Therefore, it must now be set explicitly.

Also, this makes git-flow work in stand-alone repositories (i.e. repos
that do not have an origin remote at all).

Also, invite users to help out on the git-flow completion for zsh.
Personal itch that needs some serious scratching :)

It disturbs the layout of the README file and nobody uses 0.1 anymore
anyway.  At least I hope (for them).

Finishing features now only update / and / if they exists, this allows you to work on a unpushed repo, or a git svn repo

Should have done this way earlier on the develop branch.

See the README file for instructions on how to use it.
