docs: Removes the source code associated with the given AST node from the
  precompiled result, provided precompilation is configured to remove
  all references to Woodman (empty "keepLevels" option).
  
  Depending on the "comment" option, the function either converts the
  original source code to a JavaScript comment or removes it altogether.
  
  Important: once this function has been executed, the children of the
  given node in the AST tree should not be updated in any way.
