I just had a quick look in the rosinstall script for v0.5.22. With only a
recursive call in class Config, method load_yaml():

        if k == 'other':
to
        if k == 'include':

self.load_yaml(rosinstall.helpers.get_yaml_from_uri(source_uri),rosinstall_source_uri)
        elif k == 'other':

On a rosinstall file that looks like:

    - include:
        uri:
http://win-ros-pkg.googlecode.com/svn/stacks/win_ros/trunk/mingw_electric.rosinstall
        local-name: ignore_this

Installs ok, added an overlay (i.e. added a repo and reran rosinstall) and
it worked also. That gets it started - it'd need a little work to get rid of
the exceptions thrown without a local-name element. The only other thing
that might be desirable (but it works fine as is) is to expand the resultant
${ROS_WORKSPACE}/.rosinstall file which currnetly looks like this after the
initial install + 2 overlays:

# THIS IS A FILE WHICH IS MODIFIED BY rosinstall
# IT IS UNLIKELY YOU WANT TO EDIT THIS FILE BY HAND
# IF YOU WANT TO CHANGE THE ROS ENVIRONMENT VARIABLES
# USE THE rosinstall TOOL INSTEAD.
# IF YOU CHANGE IT, USE rosinstall FOR THE CHANGES TO TAKE EFFECT
- include: {local-name: ignore_this, uri: '
http://win-ros-pkg.googlecode.com/svn/stacks/win_ros/trunk/mingw_electric.rosinstall
'}
- svn: {local-name: eros, uri: '
https://code.ros.org/svn/eros/tags/diamondback'}
- svn: {local-name: ycs, uri: 'svn://
yujin.dnsdojo.com/control/ycs/tags/latest'}
