May I suggest a different first step to make the help output more readable?
Do we really need two lines of help output for each pair of --enable-xxx
and --disable-xxx? It would be sufficient to document only one variant
if the other variant is always supported, too. My favourite is a pattern
like this:
--disable-xxx disable xxx support (default: enabled)
--disable-xxx disable xxx support (default: auto detected)
--disable-xxx disable xxx support (default)
A final hint could say "Instead of --disable-xxx you can also enforce a
feature with --enable-xxx".
I like alphabetized sorts but would keep groups like the different
selections for the gui interfaces. Those could be largely reduced if we
used libvnc. That would also fix bugs and reduce the efforts needed for
maintainance of QEMU, but that is a different topic :-)
