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).

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.

This change makes it legal to pass a struct value as receiver
outside the package declaring the struct even if the respective
struct type has non-exported fields.
This is a backwards-compatible language change motivated by the
fact that it is already possible to circumvent the assignment
restriction when calling methods through interfaces (see issue
1402).

Prior to this CL, there were two requirements about the
package name main.
1. The package that sits at the root of the import graph
(the one where program execution begins)
must be named main.
2. No other package in the program can be named main.
This CL only removes requirement #2, which can be done
without changing any other Go documentation.
The new wording and formatting is such that removing
requirement #1 can be done by deleting a single line,
but making that change is explicitly outside the scope
of this CL, because it would require changes to other
documentation at the same time.

These are syntactical changes to better reflect the communication
operator's new status in the language.
- sending to a channel is now done via a send statement
- there is no binary communication operation anymore which
leads to a reduction of the number of precedence levels
from 6 to 5 (yeah!)
- small semantic change: since a send operation is not part
of the expression syntax anymore, a <- send operator is
binding weaker than any other operator now
- receiving from a channel is done as before via the unary
receive expression
- communication clauses in select statement now can contain
send statements or receive expressions

The default float type is not very useful but for the most basic applications.
For instance, as it is now, using the math package requires conversions for float
variables (the arguments for math functions are usually float64). Typical real
applications tend to specify the floating point precision required.
This proposal removes the predeclared types float and complex. Variable declarations
without type specification but with constant floating point or complex initializer
expressions will assume the type float64 or complex128 respectively.
The predeclared function cmplx is renamed to complex.

Regular expressions may now be used in conjuction with full text
search. Godoc will show the first 10000 occurences in the source
code and highlight the respective text segments.
- added new flag -testDir to specify a small directory for testing
(fast index creation; default = "")
- use new FormatText function to format text and Go source
code in HTML, supporting multiple kinds of text selections
simulatenously); this replaces the uses of go/printer
Stylers
- for now removed currently unused mechanism for identifier-
specific JS popups (will come back in some form once we
have type or other useful information)
- various typo fixes and minor cleanups throughout
Missing:
- indexing of non-.go files
