This is not a language change.
Added paragraphs specifying which conversions
yield results that are constants.

This is (indirectly) a language change. Per e-mail discussion
on golang-dev.
Fixes#1943.

- Added some additional examples.
- 6g appears to implement this semantics already.
Fixes#658.

Note: This is not a spec change.
The spec was not clear on the result type of
constant shift expressions. Made it more
explicit and added additional examples.
Also: Remove paragraph on send expressions (they
are statements, now).
Fixes#1708.

This CL:
-- removes Response.RequestMethod string
-- adds Response.Request *Request
-- removes the finalURL result parameter from client.Get()
-- adds a gofix rule for callers of http.Get which assign
the final url to the blank identifier; warning otherwise
Caller who did:
res, finalURL, err := http.Get(...)
now need to do:
res, err := http.Get(...)
if err != nil {
...
}
finalURL := res.Request.URL.String()

This CL proposes some subtle language changes
in an attempt to clarify the semantics of range
clauses and simplify uses of maps.
- nil maps behave like empty maps; but attempting
to set a value in a nil map causes a run-time panic
- nil channels are never ready for communication;
sending or reading from a nil channel blocks forever
- if there is only one index iteration variable in a
range clause and len(range expression) would be a constant,
the range expression is not evaluated.
(was discrepancy with len/cap before)
- the notion of what is a constant expression len(x)
for (pointer to) arrays x has been generalized and
simplified (can still be syntactically decided)
(before: more restrictive syntactic rule that was not
consistently implemented)
Fixes#1713.

Fixes a JS crash which prevented the automatically generated

No language change.
- added a few examples with parentheses
- added a corresponding sentence to assignments
(this explicitly permits: (_) = 0, currently allowed by 6g,
gofmt, but marked as an error by gccgo).

The CL introduces inconsistencies with respect to
the use of parentheses/grouping of receive operations.

I hope.
Also this picks up an update to go_tutorial.html that should already have happened.
