Comment 1:

I recognize this :)
Options are to allow dist env to write to a file, or to make all verbose messages print
to stderr.
The first is a smaller change to cmd/dist, but also requires a change to the build
scripts. The second option is a bit more sweeping, but at least leaves everything but
cmd/dist alone.

I am not sure which option is preferred. Feel free to do what you think is right. If you
are wrong, reviewers will correct you and, hopefully, explain why.
