7839521335 Automated g4 rollback of changelist 35383.
*** Reason for rollback ***

roll back the changes to the tutorial programs (only) since they
break the automated processing used to create the tutorial.

*** Original change description ***

apply gofmt to the LGTM-marked files from 34501
that have not changed since I applied gofmt.

53440da835 Factored out boilerplate from all html docs in doc directory:
- the first HTML comment in those files is extracted as page
  title when serving them
- lib/godoc.html is top-level template for all pages served
- experimented a bit with package documentation layout
  (feedback welcome)
- various related cleanups

TODO:
- The / page (doc/root.html) content repeats links that are
  in the navigation bar. It needs to be cleaned up.

  (this is the only change to the Conversions section; the rest of the text is just moved;
  old line: 4043, new line: 3078)
- fixed syntax of composite literals (parens are allowed around LiteralType)

b817e97961 change code font to "monospace", which will
let the browser use the font the user has set up
as the default fixed-width font, instead of forcing Courier.

also set the size to 100%, which means 100% of the
font size in the surrounding text.  this looks a little
better in the main body but much better when the
code is in a heading (like Package unsafe).

698c6c00a0 A step towards "externalizing" some Go docs.
+ style sheet: like code.google.com but less feature-ful
+ JS with table-of-contents generation
+ tweaked go_spec.html and go_mem.html to use new style+JS
+ static-HTML-ified a few other Go docs:
  + static HTML versions of some wiki pages (which I'll turn
    into links to these pages).

A notable thing that is _not_ in this changelist: any change
to the godoc tool or whatever thing generates http://go/godoc

a0bcaf4c00 Change os.Error convention:
echo back context of call in error if likely to be useful.

For example, if os.Open("/etc/passwd", os.O_RDONLY)
fails with syscall.EPERM, it returns as the os.Error

	&PathError{
		Op: "open",
		Path: "/etc/passwd"
		Error: os.EPERM
	}

which formats as

	open /etc/passwd: permission denied

Not converted:

	datafmt
	go/...
	google/...
	regexp
	tabwriter
	template

60ce95d7a1 code changes for array conversion.
as a reminder, the old conversion
was that you could write

	var arr [10]byte;
	var slice []byte;
	slice = arr;

but now you have to write

	slice = &arr;

the change eliminates an implicit &, so that
the only implicit &s left are in the . operator
and in string(arr).

also, removed utf8.EncodeRuneToString
in favor of string(rune).

5958dd6f94 Suggested tweaks up to package section.
Major ones:
* Be consistent: "numeric type" and "arithmetic operator".
* if/swtch take "simple statement" not "short variable declaration".
* There was a comment that implied for x,y := range z() might
  evaluate z() multiple times.  I deleted it.

5af7de3fe3 Updated the section on Types.
Moved assignment compatibility to its own small section. Although most rules are type-specific,
some are not and it reduces redundancy to combine them.
Also, more experimentally, wrote a section on comparison compatibility.
