[PATCH 09/19] Finally make remote helper support useful

[Sverre Rabbelier <srabbelier@gmail.com>]

From: Johannes Schindelin <johannes.schindelin@gmx.de>

The common case for remote helpers will be to import some repository which
can be specified by a single URL.  Rather than supporting those who say
that Git is really complicated, let's be nice to users so that they will
be able to say:

	git clone hg::https://soc.googlecode.com/hg/ soc

	I decided to not allow 'hg+https' format, since clone does
	not deal well with that syntax (it checks to see whether
	there is a ':' in the url or not).
