But when I generated my new version with the new tool, and did a diff to the prior version, it showed many more differences than just the intended ones, due to formatting differences. That was distracting, so I chose to keep using the old tool for the time being.

OK. IMO there is no single best answer.
Sometimes the current approach, that shows every formatting difference, 
is a good thing for spotting unintended consequences.

Other times I would like to suppress some things. (E.g., whitespace 
changes, changes in headers that repeat on every page, changes to page 
numbers in the TOC, etc.)

Maybe diff could have a selectable severity level.
