We now have "magic" to automatically handle `brew cask` and `brew bundle`
calls without needing to tap those taps manually beforehand. Let's reflect that
in this wording for consistency.

Not every Linux system has a pre-installed `uuidgen` command (Debian
has a package `uuid-runtime` but doesn't install it by default). In
contrast, `/proc/sys/kernel/random/uuid` is always available on a modern
Linux system and produces type/version 4 UUIDs, just like `uuidgen`.

Closes #416.

Avoid writing an empty UUID to the Git configuration file and disable
analytics temporarily to avoid sending bogus data with an invalid UUID.

If `bin/brew` happens to be symlinked to `/brew`, `/bin/brew`, or some
similar location or (worse yet) Homebrew is installed to `/`, then
computation of the prefix and/or repository path could break down and
result in an invalid or empty path.

This is inspired by `safe_system` with basically the same implication
(fail on error), making the name a lot less confusing and avoiding a
clash with the `chdir` function previously defined in `bin/brew`.

This is inspired by `quiet_system` with basically the same implication

This commit adds a --tap option to the create command such that a user
could create a formula in a specified tap instead of the core.

The `ensure` block can be reached before the tab is modified (and thus
before `original_tab` gets populated). Avoid raising an exception when
attempting to restore a tab that hasn't been modified yet, e.g. because
relocating some of the Mach-O binaries failed.

* Fix regression caused by 05649cee
* Use `Tap#formula_file?` to filter formula.

* audit.rb: require https for ftpmirror.gnu.org

The situation is similar to other mirror redirectors: the server
may subsequently redirect to an insecure url. But it's a step.

* manpage: update HOMEBREW_NO_INSECURE_REDIRECT section
