- Use the `Formula.cache` and `Cacheable` rather than rolling our own.
- Use keyword arguments instead of `options = {}`
- Improve readability in general
- This also required auto-fixes for Layout/EmptyLinesAroundBlockBody and
Layout/InconsistentIndentation once the auto-fixer had got rid of the
"redundant begin"s.
In a number of Cask specs, the value of the `homepage` stanza is currently set
to https://example.com. As of 2018-11-28, the TLS certificate served by
example.com seems to be expired, possibly due to an oversight on ICANN’s side.
While the certificate is certainly going to be renewed soon, it would be
desirable for Homebrew’s test result to be less dependent on ICANN’s actions.
This commit changes the homepages of all test Casks to http://brew.sh, whose
domain and TLS certificate are both controlled by Homebrew.
Also, don't delete them after that. This means that `brew postinstall`
becomes a way to easily reinstall configuration files for any formula
without needing any changes to any bottles or requiring a reinstall.
