- define "0-sized"
- add clarifying sentence to pointer comparison
- removed notion "location" which was used only in pointer comparisons
and which was never defined
Fixes#2620.

gofmt likes to put lines like
// STOP OMIT
two blank lines from a closing brace, creating an ugly space inside
<pre> blocks in some of these files. This change resolves this issue.

This change guarantees that whether the line ending convention
when the source is created includes carriage returns is irrelevant
to the value of the string. See issue 680.

This is a spec correction, not a language change.
The implementations have behaved like this for years
(and there are tests to that effect), and elsewhere in
the spec true and false are defined to be untyped
boolean constants.

This has always been true, but we lost it from the spec
somewhere along the way, probably when we disallowed
the general 'pointer to anything sliceable' slice case.
R=gri
CC=golang-dev
https://golang.org/cl/5437121
The special case in the spec is that you can take the
address of a composite literal using the & operator.
A composite literal is not, however, generally addressable,
and the slice operator requires an addressable argument,
so [3]int{1,2,3}[:] is invalid. This tutorial code and one bug
report are the only places in the tree where it appears.

To structure larger sections of comments in html output headings
are detected in comments and formated as h3 in the generated html.
A simple heuristic is used to detect headings in comments:
A heading is a non-blank, non-indented line preceded by a blank
line. It is followed by a blank and a non-blank, non-indented line.
A heading must start with an uppercase letter and end with a letter,
digit or a colon. A heading may not contain punctuation characters.

The Set type is gone. Instead, templates are automatically associated by
being parsed together; nested definitions implicitly create associations.
Only associated templates can invoke one another.
This approach dramatically reduces the breadth of the construction API.
For now, html/template is deleted from src/pkg/Makefile, so this can
be checked in. Nothing in the tree depends on it. It will be updated next.

The allowed conversions before and after are:
type Tstring string
type Tbyte []byte
type Trune []rune
string <-> string // ok
string <-> []byte // ok
string <-> []rune // ok
string <-> Tstring // ok
string <-> Tbyte // was illegal, now ok
string <-> Trune // was illegal, now ok
Tstring <-> string // ok
Tstring <-> []byte // ok
Tstring <-> []rune // ok
Tstring <-> Tstring // ok
Tstring <-> Tbyte // was illegal, now ok
Tstring <-> Trune // was illegal, now ok
Update spec, compiler, tests. Use in a few packages.
We agreed on this a few months ago but never implemented it.

An experiment: allow structs to be copied even if they
contain unexported fields. This gives packages the
ability to return opaque values in their APIs, like reflect
does for reflect.Value but without the kludgy hacks reflect
resorts to.
In general, we trust programmers not to do silly things
like *x = *y on a package's struct pointers, just as we trust
programmers not to do unicode.Letter = unicode.Digit,
but packages that want a harder guarantee can introduce
an extra level of indirection, like in the changes to os.File
in this CL or by using an interface type.
All in one CL so that it can be rolled back more easily if
we decide this is a bad idea.

- the low-level assembly functions Syscall, Syscall6, and so on
return Errno, not uintptr

This contains the files that required handiwork, mostly
Makefiles with updated TARGs, plus the two packages
with modified package names.
html/template/doc.go needs a separate edit pass.
test/fixedbugs/bug358.go is not legal go so gofix fails on it.

1. Generate TOC for package pages using template,
instead of using JavaScript magic. This makes the
pages generated by godoc -html easier to export
to other systems.
2. Make TOC one column. It's hard to do two columns
portably without invoking JavaScript.
3. Since the TOC is only one column, show full type
signatures for functions and methods. Many times
that's all you need to see anyway.
4. Name the section after the TOC "Overview".
Naming it something is important, to set it off
from the TOC and so that there's a quick link to
it in the TOC.
For now, some illustrative examples:
http://swtch.com:6060/pkg/io/http://swtch.com:6060/pkg/strings/http://swtch.com:6060/pkg/tabwriter/http://swtch.com:6060/pkg/unicode/Fixes#1982.

This CL introduces the go.Example type and go.Examples functions that
are used to represent and extract code samples from Go source.
They should be of the form:
// Output of this function.
func ExampleFoo() {
fmt.Println("Output of this function.")
}
It also modifies godoc to read example code from _test.go files,
and include them in the HTML output with JavaScript-driven toggles.
It also implements testing of example functions with gotest.
The stdout/stderr is compared against the output comment on the
function.
This CL includes examples for the sort.Ints function and the
sort.SortInts type. After patching this CL in and re-building go/doc
and godoc, try
godoc -http=localhost:6060
and visit http://localhost:6060/pkg/sort/
