[PATCH] Do not ignore errors from tar

[Demi Marie Obenour <demiobenour@gmail.com>]

These would be ignored due to a missing -o pipefail in the shell script.
As a result, listing nonexistent s6-rc-compile inputs would cause a
broken image to be successfully built.

Also remove newlines that broke Vim syntax highlighting.
