I'm actually okay with the wording in the patch above (the above text
seems particularly long-winded). My personal opinion is that we should
try and leave it close to the original as possible in case other
versions of OS 9 and/or OS 8 check different parts of the copyright
string if someone is interested enough to try and boot them with QEMU ;)
