cmd/vet: setting composites flag false doesn't do anything

[gopherbot]

by herbert@clypd.com:

Create the test files like this (shell)

mkdir vet_bug
cd vet_bug
export GOPATH=`pwd`
mkdir src
cd src
mkdir a
cat <<EOF > a/a.go
package a

type Tuple []string
EOF
cat <<EOF > main.go
package t

import "a"

var x = a.Tuple{"a", "b", "c"}
EOF
go build ./...
go tool vet -composites=false ./...


This creates a directory structure like this with GOPATH set

vet_bug
└── src
    ├── a
    │   └── a.go
    └── main.go

What is the expected output?
nothing

What do you see instead?
src/main.go:5: a.Tuple composite literal uses unkeyed fields

Which operating system are you using?
mac os x 10.9

Which version are you using?  (run 'go version' or 'gccgo --version')
go version go1.2 darwin/amd64

Comment 1 by herbert@clypd.com:

Language in the documentation suggests that I can disable the associated checks (i.e.
composites) by passing in the associated flag, but in fact it does the opposite, where
by passing in the flag, it enables that particular set of checks.  
I was able to find a workaround in the meantime, by just passing in the set of flags for
the tests I want to run, but it does look kind of ugly.
