[Qemu-devel] [PATCH ] qemu-help: add category headlines

[Marcel Apfelbaum <marcel.a@redhat.com>]

This patch follows Markus Armbruster suggestion:

A possibly better way to group help by category: instead of adding
categories to each line, add category headlines, like this:

    Controller/Bridge/Hub devices:
    name "NAME", bus "BUS"...
    ...
    USB devices:
    name "NAME", bus "BUS"...
    ...
    Storage devices:
    ...

This way, showing devices with multiple categories once per category
actually makes sense.

Note that the "categories to each line" is kept for 2 reasons:
1. Preparation for multifunction devices
2. Ability to grep by category
