None of these made sense as end-user commands.

Use active voice when applicable, better verbs & adjectives, preposition usage, proper tense, etc.

This improves both test coverage, makes it easier to use a profiler and
a debugger.

The `bash`, default one is broken on `zsh`.

Fixes Homebrew/homebrew#23835.

On Unix, the path separator is ':', whereas on Windows,
it is ';'. This is the first of a series of patch to bring
macbrew's and winbrew's codebases closer together.

The main places the magic constant ':' was being used were:
  - the $PATH environment variable
  - CMAKE-related environment variables
  - pkg-config related environment variables

We add the bins from all deps instead. Rationale: formula find and use eg. GNU-coreutils versions of things and then break. Only allow formula to use tools that they depend on and expect.

I want to go further and only add include paths etc. for dependencies, I have done some work on this, but I fear it may be impossible. If an include path is eg. /usr/local/lib/foo/include, is it possible to know if this path is bad? Not always AFAICT.
