yeah ok, but the commands really are not executed.  I have an option
dry-run in the script, which sets "prog_log=true".  Then there are
a bunch of verbose commands in the block, none of get touched.

The fact that I can see the trace on the terminal instead of the logfile
should prove that it shows what bash is actually doing.

In the meantime I upgraded to "version 4.0.33(1)-release
(i686-pc-linux-gnu)", which didn't change anything.

Nonetheless you seem to implicitly confirm what I had originally
planned:  the block should execute and both its stdout and stderr should
get piped into the logger.
