Difftastic works really hard to find similarities between the before and after file. Sometimes this works wonderfully (see first screenshot) and sometimes it goes way too far (see second screenshot). It's matched up a few variables and semicolons from adjacent functions!

Many of the GNU manuals are incredibly good. For example, the diff manual includes worked examples: https://www.gnu.org/software/diffutils/manual/html_node/Example-Context.html What's the secret? My docs are getting better, but they're not on this level.
