Well, my use case, and the reason for my patch is thus:

I have one USB stick under 2GB, that I want to keep as compatible as
possible to the USB-Zip boot option in BIOS. So I want to use partition
4 instead.

On the other hand, I have another stick where I don't need to have the
partition as number 4, but I'll have two, and I'd rather the Windows
system booted from the second partition doesn't see the first (I'm still
testing if changing the first to "Hidden ..." works).

To prevent having to check and edit isohybrid, I've decided to add
options to it!

Whether you should add support for it in libisofs and xorriso, it's not
up to me, but more options should hurt, no? ;)
