From e4bd81f903362d998f7bfc02095935408aff0bc5 Mon Sep 17 00:00:00 2001
From: Robert Griesemer <gri@golang.org>

Subject: 1) Change default gofmt default settings for    parsing and printing
 to new syntax.

   Use -oldparser to parse the old syntax,
   use -oldprinter to print the old syntax.

2) Change default gofmt formatting settings
   to use tabs for indentation only and to use
   spaces for alignment. This will make the code
   alignment insensitive to an editor's tabwidth.

   Use -spaces=false to use tabs for alignment.

3) Manually changed src/exp/parser/parser_test.go
   so that it doesn't try to parse the parser's
   source files using the old syntax (they have
   new syntax now).

4) gofmt -w src misc test/bench

3rd set of files.
