Nigel Tao e55fdff210 bufio: make Writer.ReadFrom not flush prematurely. For example,
many small writes to a network may be less efficient that a few
large writes.

This fixes net/http's TestClientWrites, broken by 6565056 that
introduced Writer.ReadFrom. That test implicitly assumed that
calling io.Copy on a *bufio.Writer wouldn't write to the
underlying network until the buffer was full.

Graham Miller 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.

Robert Griesemer 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
