kre f5deb3ba25 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.
