Tcl throws an exception if the command run via system exits nonzero or
produces any output on stderr. (You can suppress *some* of this --- but
that was added only recently and not everyone ran out and immediately
rewrote to use the new syntax.) So catch is about catching that exception,
not output. The output is the string result of system.
