module Compat
`odisabled` will still return for a formula in `.brew`. This means `EOS.undent` returns `nil` and the formula cannot be parsed. Instead return the actual string in this case to avoid e.g. patches blowing up with `nil` strings. Fixes #4049.
Move various `odeprecated` to `odisabled` and delete uses of `odisabled`.
These have all been deprecated/compat for a while.
