I see this is following some established convention in the file, but is
there really not a way to make this pass without directing stderr to
/dev/null? It makes ad-hoc debugging when reviewing harder.


I tried just removing it, but then (in an earlier test case) the
"test_subcommand" fails because it can't find the line we're looking
for, so us piping stderr to /dev/null impacts our trace2 output?
