Problems passing multiple arguments to --qemu-options for adt-virt-qemu from adt-run

I'm trying to pass multiple arguments to adt-virt-qemu's --qemu-options from adt-run and having issues:

Hello Max,

Indeed the first '-' in the value confuses the option parser. You have
to use --qemu-options='...', then it will work as intended. This is
not related to multiple arguments.

The manpage shows this correctly. Unfortunately there's no way to
make argparse's --help output use an '=' instead of a space.

Excellent, thanks, that works much better!
