That would be really helpful for any admin menu command that returned
an error. The other day when I was affected by the buffer overflow bug
for long hostnames, the observed behavior was that clicking
simpleusb-tune-menu in the menu would immediately go back to the menu.
I had to run the command from a bash shell before I could see that
there was an error message and non-zero return code. Luckily I was the
one working on it because the repeater owner I was working with isn't
as familiar with Linux and probably wouldn't have thought to try that.
The admin menu hides the complexity of bash, but in its current form
it also hides all of the error detection and reporting functionality
we have in bash.
