This is really, really slow at the moment for a few reasons: - it goes through the list of revisions twice - it checks many more revisions than it needs to Even after these improvements it's still by far the slowest audit so am also making it a `--git` only audit. Additionally, to further improve default `brew audit` performance do not run `brew style` checks when doing `brew audit` with no arguments. `brew style` can be run quickly and efficiently on all of a tap (and is cached) so no need to duplicate it here.
