I don’t know how maintainers are going to feel about this, to be
honest. If it’s too clunky, perhaps we could externalise the entire two
main blocks here and then require that file into the audit instead?

Basically, I’m pushing changes here to better detect a wide-array of
SSL/TLS available links that either have no auto-redirect in place or
is a common linking error in formulae. I haven’t spotted any false
positives yet, but obviously, feel free to try and break the changes
and I’ll fix as necessary ;).

IMO, this would allow us gradual updates without having to mass-update
everything at once and stress the bot and inform users they have
hundreds of updates pending when really it’s just style/basic changes.

Check the executable is present to give a better error message if it isn't.

Don't want to enforce more than we need to.

Just equalises a little how we treat HEAD and devel. The former already
fails if there isn’t a head defined, It seemed logical that devel
should fail in the same way.

The --help flag is intercepted by brew.rb and prints the global usage
string. `irb` is never called when `brew irb --help` is executed.

* Moved the `pip` homepage to something that points more directly at
`pip`.
* Adds a note on `test do`. All the maintainers and the bot check the
existence of such things these days, but I guess if anyone stumbles
across the document it’s useful to say.
* GiX is formally dead, and has two blessed forks.
* Typo on contributor.

If the `Gem.user_dir/bin` is not already in the PATH it'll complain
unnecessarily (as we add it to the PATH ourselves) so just add it to the
PATH before running the install.
