      This fix makes the goFilesPackage helper function print the errors from
      package imports and exit similar to how the packagesForBuild function does.

      Without this change, when invoking "go build *.go" with, for example,
      an old import path, the following stack trace is generated:

      panic: runtime error: invalid memory address or nil pointer dereference

      goroutine 1 [running]:
      go/build.(*Tree).PkgDir(...)
              /opt/go/src/pkg/go/build/path.go:52 +0xfb
      main.(*builder).action(...)

      main.main()
              /opt/go/src/cmd/go/main.go:126 +0x2d8

Fixes #2865.

The practice encourages people to think this is the way to
create a bytes.Buffer when new(bytes.Buffer) or
just var buf bytes.Buffer work fine.
(html/token.go was missing the point altogether.)
