[antlr-interest] Not able to preserve formatting while saving the file

[Monty Zukowski]

This is not the easiest thing to do.  Ter's answer using the 
TokenStreamRewriteEngine assumes no trees, just a parser pass.  There 
is another article on preserving whitespace on antlr.org using hidden 
token streams and attaching to the tokens.

In the C grammar I think I recorded the column and line info and would 
add in the indentation and lines as needed when I was emitting a token 
that wasn't at the current position.
