Improve quoting in xtrace (-x) output ... if a string ("word") to be
output includes a single quote (') then see if using double-quotes to quote it is reasonable (if no chars that are magic in " also appear). If so, and if the string is not entirely the ' character, then use " quoting. This avoids some ugly looking results (occasionally). Also, fix a bug introduced about 20 months ago where null strings in xtrace output are dropped, instead of made explicit (''). To observe this, before you get the fix: set -x; echo '' (or similar.) Move a comment from the wrong place to the right place.
