This fixes issue #59.

This implementation does not rely on Bash-specific functionality.

This is useful for small projects.

Simply step aside to the master branch instead.

For example, you could set the versiontag prefix to be:

    git config --global gitflow.prefix.versiontag "production/\$(date +%Y/%m/%d/)"

which would result in tag names like:

    production/2010/09/22/my-hotfix-or-feature-name

NOTE:
Although this is a useful addition in the current version of git-flow,
in a future reimplementation of it in Python, this will be replaced by
hook scripts, so be sure not to rely on this feature too much for now.

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).
