From reading https://github.com/orgs/Homebrew/discussions/3328: I initially thought we should just change "Updated" to "Modified" when appropriate. After conversation with Bo98, though, I thought more and saw that we're already checking for outdated formulae here so, rather than ever traverse through the formula history, look at the outdated formula and list them unless we've set `HOMEBREW_UPDATE_REPORT_ALL_FORMULAE` in which case we show the modifications. While we're here, also do a bit of reformatting and renaming to better clarify intent.
