Personally, I find such descriptions to be more easily readable (or rather more easily visually separable from other parameters) if they’re indented. I understand that two other parameters’ descriptions aren’t indented either (but one is), so in the end it’s your choice. (But I thought a little nudging couldn’t hurt.) So either way (with *6.0): Reviewed-by: Max Reitz <mreitz@redhat.com>
