Documenting minimizing diffs for ease of review

Suppose we have some lines that are close to 80 chars long

first text ... end first text.
second text ... end second text.
third text ... end third text.

and if the first line needs some sort of modification that would push it past 80 chars, we can either restructure the entire paragraph of raw rst so it looks tidier, but resulting in 4 lines of git diffs

first text plus some more ...
end first text. second text ...
end second text. third text ...
end third text.

or diffs can be minimized (but with an 'uglier' raw rst), such as like

first text plus some more ...
... end first text.
second text ... end second text.
third text ... end third text.

I think that for ease of reviewing, as well as to maintain a more useful git history, that the second is preferred in general but I haven't found it in the style guide, so maybe it can be added there if there's consensus on it?

Read the documentation style guide linked in the issue and review the existing discussion about minimizing diffs. Add guidance only if the project agrees on the preference, with examples showing the recommended wrapping style; the style guide should clearly document the convention when done.
