Hbc::CaveatsDSL#path_environment_variable

DSL. Each method should handle output, following the convention of
at least one trailing blank line so that the user can distinguish
separate caveats.

( The return value of the last method in the block is also sent
  to the output by the caller, but that feature is only for the
  convenience of Cask authors. )
