Username prompt from code.cloudfoundry.org/cli, then seems to hang

[tim-gp]

Note that I did try entering my username.

Reproduce with:

$ mkdir -p ~/golang/src/mypjt && \
 export GOPATH=~/golang && \
 cd $GOPATH/src/mypjt && \
 echo 'package main
 import (
 _ "code.cloudfoundry.org/cli"
 )' > app.go

$ dep init -v
