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

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.

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