Show DMG agreements by default

[vitorgalvao]

References #720. Some preliminary work done (and abandoned) in #8231.

How the system should work:

• Show DMG agreements by default.
  • This is a blocking operation (i.e. the user has to type y or n to agree or not, before continuing).
  • The license is redirected to less, for easy reading and so terminal output doesn’t get cluttered.
    • If they agree, the installation continues.
    • If they disagree, the installation of that particular package aborts and the rest (if any) continue.
• Have a --blindly-accept-licenses¹ flag that will auto-accept agreements for that command.
  • This also works if set in HOMEBREW_CASK_OPTS.
  • In this case, the license won’t even be printed to output, and the user won’t be warned.

---

¹ The use of “blindly”, as suggested by @MattiSG, has power.

It's worth mentioning that implementation of this feature is blocked by #8231. There's nothing to stop us from picking up @claui's work and moving forward, though.

[vitorgalvao]

@claui has been absent from the project for a long time, and hasn’t even replied on that issue so we should consider that dead, and just pick up whatever’s useful.

Just popping in to reiterate my previous comment. A simple one-line message, whether the default or with another flag, telling the user what they blindly agreed to would be welcome.

@vitorgalvao, I think this is actually implemented, but only shown with --verbose.

[vitorgalvao]

@reitermarkus But that is that ever a blocking operation that the user has to agree to before continuing?

[reitermarkus]

No, it doesn't block. Honestly, I think we should just close this. Nobody has complained or shown any interest in this in 4 years.
