Sorry for spamming, this is the correct output - filenames in the last
one were confusing.

./scripts/bloat-o-meter ./busybox.old ./busybox.new
function                                             old     new   delta
.rodata                                           140405  140177    -228
------------------------------------------------------------------------------
(add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-228)           Total: -228 bytes
