  BREAK: manual.yaml: don't set any default env vars
  
  Remove the 'MAKEFLAGS' and 'V' defaults.
  
  Now that there is a specialised 'make' element, these make-specific
  defaults don't make sense here. This element is meant to be a blank
  slate for folks to build on.
  
  Note that this is a breaking change, that will require some users to
  make changes to their .bst files if they are expecting these environment
  variable to be set.
  
  _versions.py: BST_FORMAT_VERSION bumped to 18.
