2010-02-25go/printer, gofmt: correct indentation after certain /*-style commentsRobert Griesemer1-1/+1
- applied gofmt to src and misc Note: This fix improved formatting of src/pkg/math/all_test.go but leads to a degradation in src/pkg/exp/4s/xs.go. The latter happened to "work" before accidentally.

2009-12-151) Change default gofmt default settings forRobert Griesemer20-301/+301
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.
