* add -work option to save temporary files (Fixes issue 2980) * fix go test -i to work with cgo packages (Fixes issue 2936) * do not overwrite/remove empty directories or non-object files during build (Fixes issue 2829) * remove package main vs package non-main heuristic: a directory must contain only one package (Fixes issue 2864) * to make last item workable, ignore +build tags for files named on command line: go build x.go builds x.go even if it says // +build ignore. * add // +build ignore tags to helper programs R=golang-dev, r, r CC=golang-dev https://golang.org/cl/5674043
