I would appreciate if it were an optional feature.

Double yuck for an incomplete refactoring. Why should a generic
histogram-drawer know about *diff*-anything (and if this is still
a diff-specific histogram-drawer, verify-pack has no business
calling it)?
I like the idea very much, but not this particular execution.
