|  | - Don't allow taking an argument. This doesn't work and never has as it
  caches the result regardless of the argument.
- Don't rely on the PATH to check for external commands. |

|  | Move some `brew doctor` checks that are pretty macOS specific so they
are only run on macOS. | 
|  | - only document HOMEBREW_* variables in the manpage (although still
  read from all the original environment variables).
- resort manpage environment variables in alphabetical order
- check the original path for trailing slashes | 
|  | Added assertion to check `HOMEBREW_LOCK_DIR.stat.mode` changes after `HOMEBREW_LOCK_DIR.chmod 0555` | 
|  | Hide these tokens to avoid malicious subprocesses e.g. sending them
over the network. Also, support using these tokens with environment
filtering and clear `HOMEBREW_PATH` from subprocesses to stop them
sniffing it. Finally, use `HOMEBREW_PATH` to detect Homebrew’s user’s
PATH for e.g. `brew doctor` etc. |
