2c2e2c5d55 more comment work. 
got rid of regexps.
primary bug fix is that // inside /* */ do not get stripped anymore,
so that the text inside

/*
int a;
// int b;
int c;
*/

is

int a;
// int b;
int c;

before, the "int b;" line was being uncommented too.

9d9a421e24 Change description of time.Time.ZoneOffset to specify east is +ve. 
Currently, the description says that +ve numbers are westwards of UTC.
Typically, timezones are specified with +ve numbers running east of Greenwich.
For example, San Francisco is specified as UTC-8. Also, when calling
time.Localtime(), the following is returned on my box in PDT:

{Year:2009 Month:10 Day:5 Hour:18 Minute:55 Second:6 Weekday:1 ZoneOffset:-25200
Zone:PDT}

Note that the ZoneOffset is negative. This leads me to suspect that the
description is mistaken.

the proc switch because the gosym interface differs from the

2210a643b7 Intersperse comments nicely when printing an AST. 
gofmt formatted source code looks pretty good already;
with a bit more fine-tuning it should be great.

printer.go:
- Implemented comment intersperse algorithm.
  The approach is a result of many trial-and-error
  experiments but at this point reasonably simple
  and open to arbitrary fine-tuning.

parser.go:
- Simplified handling of lead and line comments
  (formerly called leading and trailing comments).
- Use a comments list instead of an array (I may
  change this back - this is not obviously better
  and uses more space).

doc.go:
- Remove comments from AST nodes that have been
  'consumed' in the documentation to avoid duplicate
  printing of them. Allows for better control of
  what is printed w/o use of printing control flags
  (which are hard to use and not fine-grained enough).

Corresponding adjustments to various clients of these
files.

introduce NodeList* type in compiler to replace OLIST.
this clarifies where lists can and cannot occur.
list append and concatenation are now cheap.
the _r rules are gone from yacc.
rev and unrev are gone.
no more lists of lists.

the representation of assignments is a bit clunkier.
split into OAS (1=1) and OAS2 (2 or more on one side).

aa1e8064b2 change HTTP access for RPC. 
1. use CONNECT instead of GET.
   CONNECT has exactly the meaning
   we want; most of the time people
   connect to ip:port; we're connecting
   to /_goRPC_

2. wait for a successful HTTP response
   before assuming we are connected to
   the RPC protocol.  this allows better
   error reporting and also keeps the
   protocol alternating between speakers,
   so that the buffering in the HTTP request
   reader cannot accidentally eat some
   RPC bytes too.

gotest sometimes hangs, but not in HTTP.

gotest -match=Unknown hangs every few runs
even in a clean client.
