A +Pager pane whose text is a diff is drawn and looked at as a diff, as a diff command pane is: git diff, show and log -p page into review

With git paging into +Pager, a diff arrived as plain text: no colour
for its sides and a right click on a hunk line searched the word. A
+Pager pane now notes, as its text is set, whether its first 64 KiB
holds a diff header or a unified hunk, and such a pane takes the diff
highlighting and the diff look every diff pane has.
