This isn't standardized, so I'm not worried about small differences between
implementations in something that happens interactively.
Bash uses the `v' option to echo commands as they are read from the temp
file and executed, and that option is inherited by subshells. ksh93
doesn't seem to echo any commands at all. I personally think the bash
behavior is more useful.
