bb7b1a11d5 bufio: drop error return for NewReaderSize and NewWriterSize
It complicates the interface unnecessarily.

Also update the go/doc Makefile.

5be24046c7 all: avoid bytes.NewBuffer(nil)
The practice encourages people to think this is the way to
create a bytes.Buffer when new(bytes.Buffer) or
just var buf bytes.Buffer work fine.
(html/token.go was missing the point altogether.)

f795bdb979 bufio: do not cache Read errors
Reader previously had cached an error from the underlying reader
and would return it on every subsequent call to Read.  The Reader
will now return the error only once, and subsequent calls will result
in a new Read call to the underlying Reader.

Fixes #1934.

1ce6245d6c throughout: fix broken calls to Printf etc.
I have written a tool to verify Printf calls, and although it's not
ready to be reviewed yet it's already uncovered a spate of problems
in the repository.  I'm sending this CL to break the changes into
pieces; as the tool improves it will find more, I'm sure.

041d978d84 bufio: change ReadSlice to match description

way for err == ErrBufferFull, making it harder for callers to

5a1d3323fe 1) Change default gofmt default settings for
parsing and printing to new syntax.

                  Use -oldparser to parse the old syntax,
                  use -oldprinter to print the old syntax.

               2) Change default gofmt formatting settings
                  to use tabs for indentation only and to use
                  spaces for alignment. This will make the code
                  alignment insensitive to an editor's tabwidth.

                  Use -spaces=false to use tabs for alignment.

               3) Manually changed src/exp/parser/parser_test.go
                  so that it doesn't try to parse the parser's
                  source files using the old syntax (they have
                  new syntax now).

               4) gofmt -w src misc test/bench
