While doing this, also normalizing the quoting in the `echo FOO | sed 
...` would be nice.  Some cases quote the argument to echo and some do 
not.  At runtime it probably does not matter because the substituted 
values will never contain whitespace, but quoting them all would make 
shellcheck more useful.

Also see patch 5 in the recent "v2" series for the marker line to 
prevent shellcheck from complaining about backticks.  It must be placed 
before the first executable line (the timestamp variable assignment) for 
shellcheck to apply it to the entire script.
