Add some `--all` flags we'll eventually migrate to to ensure that we'll
eventually require their usage to read all formulae. Where we need to
do stuff later, add some comments.
- This also required auto-fixes for Layout/EmptyLinesAroundBlockBody and
Layout/InconsistentIndentation once the auto-fixer had got rid of the
"redundant begin"s.
Don't perform an incremental update from a report or list of formulae if
the cache is currently empty.
Also, remove some accidentally remaining debugging output.
This makes use of both the existing interfaces and could use the
existing cache file but we'll create a new one and cleanup the old one
to avoid issues and use a more consistent name.
