I cannot create an issue on the tracker for some reason, so here it is:
go vet contains this snippet:
if types.IsAssignableTo(typ, errorType) || types.IsAssignableTo(typ, stringerType) {
It's getting the wrong answer: It claims
interface {
f()
}
or even
interface {
f() float64
}
matches the Error and Stringer interfaces. Both of them. This causes a test failure:
$ go test code.google.com/p/go.tools/cmd/vet
BUG: errchk: testdata/print.go:124: missing expected error: '"for printf verb %s of wrong type"'
$
This worked until very recently.

The old code only got it right for Stringers (etc.) and a few other simple cases.
But the rule used by fmt.Printf for non-Stringers is that pointers to structs
print as pointers, the rest must satisfy the format verb element-wise.
Thus for example
struct {a int, b []byte}
prints with %d and %q (sic) but not %g.

Also move some common code from main.go to handlers.go, and
exclude remotesearch.go from the appengine build (it is only
relevant to the command line interface).

The analysis for types.Array was just missing. It's the same as a slice,
but we can't share code easily because the types differ, so we just dup it.

First, %v and %T accept any arguments, so they should never warn.
Second, pointer types were not handled in matchArgType.
Third, the default response for matchArgType should be false.

Phrases like "returns whether or not the image is opaque" could be
describing what the function does (it always returns, regardless of
the opacity) or what it returns (a boolean indicating the opacity).
Even when the "or not" is missing, the phrasing is bizarre.
Go with "reports whether", which is still clunky but at least makes
it clear we're talking about the return value.

I'd like to make vet work as a filter, but passing /dev/stdin as a
command line argument doesn't work. This at least makes it not panic.

The exported Server becomes handlerServer, and part of Presentation
now. Presentation is also now an http.Handler with its own
internal mux (a detail, which might go away).
main.go becomes ever simpler.

Allmost all uses of go/types that wanted the type
information computed, installed callback functions
that stored the information in maps. Most of the
time this is the only thing that could be done because
there is no guarantee that types are completely set
up before the end of type-checking.
This CL removes the respective Context callbacks in favor
of corresponding maps that collect the desired information
on demand, grouped together in an optional Info struct.

cmd/godoc/godoc.go is now merged into main.go, which is now
only 530 lines.
App Engine mode is still broken, but should be easy to fix up.
(just needs a global *godoc.Presentation created in init)

The plan for godoc:
- Copy godoc source from the core repo to go.tools (this CL).
- Break godoc into several packages inside go.tools, leaving a package
main that merely sets up a local file system, interprets the command
line, and otherwise delegates the heavy-lifting to the new packages.
- Remove godoc from the core repo.
- Update cmd/go to install this godoc binary in $GOROOT/bin.
- Update misc/dist to include godoc when building binary distributions.

Details:
- added support for complex numbers as distinct from floats:
%[efg] allows complex; %b does not.
- %p: only Signature, Map, Chan, Slice, unsafe.Pointer allowed.
- %s: allow []byte.
- allow a verb to match map[K]V and []T if it matches K/V/T,
e.g. %d now matches []int. i.e. matching is recursive.
- use go/types' constant folding. literal() is gone.
- group cases together.
Added tests.

This requires a little more tree rewriting to put a block around the if of an "else if".
More tests too.
