To reproduce the problem:

1. Do a fresh installation of the latest Go release (1.3.3) from source, as described in
http://golang.org/doc/install/source

2. Install all the tools with 'go get code.google.com/p/go.tools/cmd/...' (again as
described in http://golang.org/doc/install/source).


What happened?

Running 'go version' prints:
'go version go1.3.3 linux/amd'

But running 'cd $GOPATH/src/code.google.com/p/go.tools/; hg branch' prints:
'default'


What should have happened instead?

Running 'hg branch' in the go.tools repo should print:
'release-branch.go1.3'


Additional information

This causes problems with tools such as godoc.  For example, browsing the source for the
standard library using 'godoc -http=:6060' doesn't work, as godoc looks in the 1.4
source location '/src/...', instead of the 1.3 location '/src/pkg/...'.  Worse still,
you can not even correct the URL in your browser by hand, as godoc will always redirect
'/src/pkg/...' to '/src/...'!
