If a numeric + argument is supplied, do not perform quote removal (pass + Q_HERE_DOCUMENT since here-doc quoting does the right thing) and + do not perform command or process subsitution. From a suggestion + by Dabrien 'Dabe' Murphy <dabe@dabe.com> based on an old bug-bash + discussion + +subst.c + - expand_word_internal: note that we have added a quoted IFS char to + istring by setting sentinel has_quoted_ifs.
