6cbdeb3f88 - fixed bug with unicode text formatting: the number of bytes 
per rune cannot be computed correctly if we have only parts
  of a rune - delay computation
- added html filtering mode: html tags and entities are ignored
  for width computations
- expanded tests:
  - extra tests for html text
  - extra tests that write text in various portions

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.

efc86a74e4 change meaning of $GOMAXPROCS to number of cpus to use, 
not number of threads.  can still starve all the other threads,
but only by looping, not by waiting in a system call.

fix darwin syscall.Syscall6 bug.

fix chanclient bug.

delete $GOMAXPROCS from network tests.

add stripped down printf, sys.printhex to runtime.

5aa7dc5daf adopt suggestions from Bentley and McIlroy (SP&E Nov 1993) 
to make qsort more robust:

	* use "ninther" to choose pivot.
	* use three-way partition to avoid quadratic
 	  behavior on all-one-value arrays.

also add tests suggested in that paper.

the immediate cause of the slowness we observed was
in fact none of these: the recursive call was sorting
data[0:m] instead of data[a:m].

also rename package to "sort" to match convention.

3c2f0ae132 * pretty printing snapshot: towards printing comments nicely 
- implemented elastic tabstops algorithm, now correct and documented
- first cut at printing comments (use -comments flag, disabled for now)
- struct field types are now aligned (using elastic tab stops)
- needs more fine-tuning

* fixed a bug in test script
* added quick smoke test to makefile and invoke it in run.bash
  instead of the full test

2d4f7ba0cd printf as we know and love it. 
Plus print[ln] with the ability to print struct values.

Note for language mavens: if a "..." function passes its argument
to another "..." function, the argument is not wrapped again.  This
allows printf to call fprintf without extra manipulation. It's good
but needs to go in the spec.

This code works:
///
package main

import fmt "fmt"
import os "os"

type T struct { s string; a, b int }

func main() {
	P := fmt.Printer();
	P.printf("%s = %d with float value %.4f\n", "hi there", 7, 123.456);
	P.println("hi there", 7, 123.456);
	P.fprintf(os.Stdout, "%s = %d with float value %.4f\n", "hi there", 7, 123.456);
	P.println(T{"x", 7, 234}, "end of struct", 8, 9);
