We could add an example on the ModularDevelopersGuide [1].  One problem
is that the switch has to rely on a prefix to be replaced.  It is
currently not possible to use http without the '.git' suffix.  For
example, with this configuration:

[url "http://anongit.freedesktop.org/git/"]
    insteadOf = git://anongit.freedesktop.org/

it is not possible to clone with

  $> git clone git://anongit.freedesktop.org/xcb/util

but only with

  $> git clone git://anongit.freedesktop.org/xcb/util.git

Do you know if there could be a http rewrite rule for that?
