The default output formatting on terminal maybe optimized for better
readability. The output for non-terminals (e.g. pipes) is never affected by
this optimization and it is always in "Field: data\\n" format.

+The cache sizes are reported as summary from all CPUs. The versions before

Note that topology elements (core, socket, etc.) use a sequential unique ID
starting from zero, but CPU logical numbers follow the kernel where there is
