2ef330ebd9 clean.bash: stop if $GOROOT is not set 
Doing rm -rf /pkg/.. blindly isn't nice.  It could have
unintended consequences.

Secondly set bash to abort on (unexpected) errors.

857d4cf1a9 Remove GOBIN in PATH dependency; don't assume cwd is $GOROOT/src 
This change removes the necessity to have GOBIN in $PATH,
and also doesn't assume that the build is being run from
$GOROOT/src. This is a minimal set of necessary changes
to get Go to build happily from the FreeBSD ports

3ca1b1d27f Continuation of issue 221 fix. When 8g or 6g or 5g are called with a 
UTF-8 string, Yconv() converts it into an octal sequence. If the
string converted to more than 30 bytes, the str buffer would
overflow. For example, 4 Greek runes became 32 bytes, 3 Hiragana
runes became 36 bytes, and 2 Gothic runes became 32 bytes. In
8l, 6l and 5l the function is Sconv(). For some reason, only 5l uses
the constant STRINGSZ (defined as 200) for the buffer size.

80e17d6797 the AST walker currently provides no way to find out how the 
nodes in the tree are nested with respect to one another.
a simple change to the Visitor interface makes it possible
to do this (for example to maintain a current node-depth, or a
knowledge of the name of the current function).

Visit(nil) is called at the end of a node's children;
this make possible the channel-based interface below,
amongst other possibilities.

It is still just as simple to get the original behaviour - just
return the same Visitor from Visit.

Here are a couple of possible Visitor types.

// closure-based
type FVisitor func(n interface{}) FVisitor
func (f FVisitor) Visit(n interface{}) Visitor {
	return f(n);
}

// channel-based
type CVisitor chan Visit;
type Visit struct {
	node interface{};
	reply chan CVisitor;
};
func (v CVisitor) Visit(n interface{}) Visitor
{
	if n == nil {
		close(v);
	} else {
		reply := make(chan CVisitor);
		v <- Visit{n, reply};
		r := <-reply;
		if r == nil {
			return nil;
		}
		return r;
	}
	return nil;
}

4c0e51cd43 Make printing faster by avoiding mallocs and some other advances. 
Roughly 33% faster for simple cases, probably more for complex ones.

Before:

mallocs per Sprintf(""): 4
mallocs per Sprintf("xxx"): 6
mallocs per Sprintf("%x"): 10
mallocs per Sprintf("%x %x"): 12

Now:

mallocs per Sprintf(""): 2
mallocs per Sprintf("xxx"): 3
mallocs per Sprintf("%x"): 5
mallocs per Sprintf("%x %x"): 7

Speed improves because of avoiding mallocs and also by sharing a bytes.Buffer
between print.go and format.go rather than copying the data back after each
printed item.

Before:

fmt_test.BenchmarkSprintfEmpty	1000000	      1346 ns/op
fmt_test.BenchmarkSprintfString	500000	      3461 ns/op
fmt_test.BenchmarkSprintfInt	500000	      3671 ns/op

Now:

fmt_test.BenchmarkSprintfEmpty	 2000000	       995 ns/op
fmt_test.BenchmarkSprintfString	 1000000	      2745 ns/op
fmt_test.BenchmarkSprintfInt	 1000000	      2391 ns/op
fmt_test.BenchmarkSprintfIntInt	  500000	      3751 ns/op

I believe there is more to get but this is a good milestone.

dc7355a974 Add flag -tabindent to gofmt: forces use of 
tabs for indentation even if -spaces is set.

Changes to gofmt:
- added -tabindent flag
- don't recompute parser and printer mode repeatedly

Changes to go/printer:
- provide new printing mode TabIndent

Changes to tabwriter:
- implement new mode TabIndent to use tabs independent
  of the actual padding character for leading empty columns
- distinguish between minimal cell width and tab width
  (tabwidth is only used if the output contains tabs,
  minwidth and padding are always considered)
- fixed and added more comments
- some additional factoring

By default, -tabindent is disabled and the default gofmt
behavior is unchanged. By setting -spaces and -tabindent,
gofmt will use tabs for indentation but do any other
alignment with spaces. This permits a user to change the
visible indentation by simply changing the editor's tab
width and the code will remain properly aligned without
the need to rerun gofmt.

db18ce2f53 gofmt: use os.Stdin instead of opening /dev/stdin 
Opening /dev/stdin can sometimes fail. For example, in the acme editor,
executing "Edit ,|gofmt" fails with:

	open /dev/stdin: no such device or address

Executing "Edit ,|ls -l /dev/stdin /proc/self/fd/0" gives:

	lrwxrwxrwx 1 root root  15 2009-09-07 02:17 /dev/stdin -> /proc/self/fd/0

to access all of the core X11 protocol requests. I have included the
generated file.

bfbb31595b Map support for template.Execute(). 
Allows the developer to pass a map either by itself for
evaluation, or inside a struct. Access to data inside
maps is identical to the current system for structs, ie.

-Psuedocode-

mp map[string]string = {
	"header" : "A fantastic header!",
	"footer" : "A not-so-fantastic footer!",
}
template.Execute(mp)

...can be accessed using {header} and {footer} in
the template. Similarly, for maps inside structs:

type s struct {
	mp map[string]string,
}
s1 = new s
s1.mp["header"] = "A fantastic header!";
template.Execute(s1)

...is accessed using {mp.header}. Multi-maps, ie.
map[string](map[string]string) and maps of structs
containing more maps are unsupported, but then, I'm
not even sure if that's supported by the language.

Map elements can be of any type that can be written
by the formatters. Keys should really only be strings.

Fixes #259.

4db3a166b2 archive/tar: Make Reader and Writer more closely follow io.Reader and io.Writer interfaces 
There's no functional change here. io gives the Read and Write methods byte slice arguments, but tar called them uint8. It's the same thing, but I think this is clearer and it matches what other packages do.

a6e1ad2733 two easy optimizations for regexp: 
1) if char class contains a single character, make it a single character.
		(this is used to quote, e.g. [.] rather than \.
	2) if regexp begins with ordinary text substring, use plain string match to start engine

8c1a627e5c add bytes.IndexByte; common case we can make fast later. 
also pick off the special case in strings.Index.   don't want strings.IndexByte
because the call site will very rarely need to allocate and we can handle the
test in the code itself.   bytes.IndexByte can avoid a common allocation.
