- by moving Position into token, scanner dependencies
are removed from several files
- clearer field names in token.Position, now possible to
have a Pos() accessor w/o naming conflicts
- added Pos() accessor
- use anonymous token.Position field in AST nodes

variable - and not noticing that the value is copied

- change src from string to []byte (perhaps should be io.Read
but that has some other disadvantages)
- simplified interface
R=r
OCL=25615

- converted more of AST and parser to use interfaces and explicit
structs for individual Go constructs (can be replaced now with
interface calls such that the parser becomes AST structure
independent, as suggested by rsc)
- added more tests (find all .go files under GOROOT)
- (temporarily) lost html links for identifiers when generating
html output
- TODO: lots of cleanups

(was cute, but not really needed)

OCL=21383

- fixed html tag generation

(not 100% correct for strings yet)

- by default consider extra newlines in src for better formatting
- additional flags for control (-newlines, -maxnewlines, -optsemicolons)
- don't print ()'s around single anonymous result types
Status: Comparing the output of pretty with the input for larger files
shows mostly whitespace/formatting differences, which is what is desired.

- Handling of overlong lines
- some esoteric cases which look funny

- changed tab width to 8 chars by default to make test run properly
- excluded 4 files that are not idempotently printed
- fixed a couple of incorrect file position recordings in parser
- fine-tuned layout engine
- white-space formatting reasonable, but not perfect
- no handling of overlong lines

To use with smaller tabs: pretty -tabwidth=4 file.go
To use with blanks instead of tabs: pretty -usetabs=0 file.go

- fine-tuned low-level printing routine for comments
