The Emacs’s Concept Index leads to (info “(emacs) Diff Mode”) paragraph two, 
where hunk is explained.

I was hoping for a Glossary at the same level as Concept Index in the Info 
navigation. 

It would collect single paragraph explanations for easy finding, perhaps, the 
top-100 most frequently used jargonwords.

My plain Emacs and Slime installation doesn’t have diffutils in Info docs, but 
*vc-diff* works.
