Go fmt on a whole source tree

I have a project currently organized something like this:

~/code/go
/bin
/pkg
/src
/proj/main.go
/some_package/package.go
/some_other_package/some_other_package.go

Now if I want to use the go fmt tool on my whole project it seems that the only way is to do it separately for each directory in my projects source tree:

go fmt proj
go fmt proj/package
go fmt proj/some_other_package

Is there some way to tell the fmt command to run on the whole source tree?

You can use three dots (...) as a wildcard. So for example, the following command will format all github.com packages:

go fmt github.com/...

This wildcard also works with other go commands like go list, go get and so. There is no need to remember such an ugly find command.
