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.
