Author: Yuan Fu <casouri@gmail.com>

    Don't print buffer when printing tree-sitter node and parser
    
    Additionally, print node's position in buffer.
    
    * doc/lispref/parsing.texi (Retrieving Node): Reflect this change in
    manual.
    * src/print.c (print_vectorlike): Remove printing of buffer, add
    printing of node position.
