Subject: [PATCH] Added comma and plus to the "don't need quoting" set.  This
 affects output from "sh -x" only (tracing execution), not quoting + is
 better, as it makes tracing commands with + and - options, or numbers, more
 consistent.

Also one minor white space change (excess indentation removed).
