Good question :)
The format mimics a EDK2's shell.
The purpose is that we will be able to add some *narrow* data fields
later without spilling out a line length.

But I admit that we don't have to do so because we have an enough width,
16 digits, for ID (or address of efi object in this case).

=== From EDK2 UEFI Shell output ===
