- This gives users of this command a `--csv` option to pass to... you guessed
it, generate a CSV that's `pbcopy`able elsewhere, for more granular
breakdowns of where a person contributed.
- Inspiration was taken from the mockup in
https://github.com/Homebrew/brew/issues/13642#issuecomment-1254535251
but without the extra dependency of the TerminalTable gem.
- Always print a condensed "total contributions" sentence.
Output:
```

We inherit some variables from the user's environment but prefix them
with `HOMEBREW_`. This is the case for (1) variables documented in the
manpage and also for some (2) variables used internally by `brew`.
We currently treat both types identically, but we should not. In
particular, we allow users to override type (1), but we don't want to do
this for type (2).
This was partially fixed in f4103e5d61526cfbf7f31540ba45ec171adc452e,
but that fix did not go far enough. Some variables that the user should
not be allowed to override can still be overridden.
This change completes the partial fix and refactors the code so that
we're less likely to mistakenly conflate the two types of variables in
the future.
- Use constants for placeholders
- Monkeypatch to set `HOMEBREW_PREFIX` consistently to placeholder
- Use environment variable to set `Dir.home` consistently to placeholder
- Use `appdir` short-circuit to set `Cask#appdir` consistently to placeholder
- Use `Cask.generating_hash!` to enable "generating mode" with these patches
- Fix `Formula#caveats` from JSON
