   godoc-formatted declarations that fit on a single line)

2) Cleaned up tabwriter implementation a bit:
   - replaced local unicodeLen() with utf8.RuneCount()
   - instead of having 2 parallel arrays for line widths and sizes,
     have a single array of cells containing a width and size
   - factored code a bit better
   - added more comments
   - added testnames to tabwriter tests
   - added more test cases and fixed a broken test case that
     now works correctly

Linux/386 is better but must never have worked;
there are still bugs surrounding the creation of new
threads in the runtime package.
