Tersely. :-)
-p --show-c-function
Show which C function each change is in.
And that's it. To describe the current behavior, it might be better
written as "Find and show the first function definition prior to the
hunk". The code in diff(1) actually just uses the regexp something
like "^[a-z]" which happens to find function definitions, but can
also find module-level variable definitions, structs, etc.
