cc352e5c1c The DejaGNU testsuite harness used by the gccgo testsuite is 
broken if you give it something which matches everything--the
.* swallows all the error messages.  Recognize some reasonable
error text directly.

cfb9425460 emit dynamically linked 6.out on darwin instead of static, 
unless given -d flag.

the resulting binary doesn't *use* any dynamic libraries,
it just has a reference to the dynamic linker and an
empty list of needed symbols and libraries.

this is enough to make 6.out binaries that can be run
under dtrace / dtruss.

cb67a8324b - fine-tuning of white space 
- 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.

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

37bdd3c3f5 - enabled comment printing by default 
- 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
R=r

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

d79f687ed8 - collect addition source position information in parser 
for end of declarations, blocks, parameter lists, etc.
- use extra src positions to more accurately print comments
- fine-tuned low-level printing routine for comments
- added better debugging support

Status:
- comments now appear at the right place (inbetween the right tokens)
- newline control needs improvement (not very hard)
- comment printing disabled for now because pretty is not idempotent
