That's a good point, and I admit I've never studied out all of the logic
of Bash init files; I assumed that it executed ~/.bashrc as a matter of

So as long as I don't need the facilities in .bashrc for the script,
then "BASH_ENV= bash ..." suffices.

In regard to "can't you do the set -x at the end of that file", (1) it's
inelegant and a PITA, and (2) it sauses sub-scripts to generate
debugging output.
