What did you do?

» go env -w GOFLAGS='-trimpath "-ldflags=-s -w"'

» go env | grep GOFLAGS                         
GOFLAGS="-trimpath "-ldflags=-s -w""

What did you expect to see?

GOFLAGS='-trimpath "-ldflags=-s -w"'

or

GOFLAGS="-trimpath \"-ldflags=-s -w\""

What did you see instead?

Yep, that's wrong. 😩

The bug is here:
https://cs.opensource.google/go/go/+/master:src/cmd/go/internal/envcmd/env.go;l=418;drc=db259cdd80eff527e8f344d678031c516167d258

We have a quoted.Join function that is used elsewhere in envcmd/env.go. It should probably be used in PrintEnv as well.
