I didn't think we bothered to make "sh -x" work robustly. I don't mind
if we do, but "git grep -E 'test_(i18n)?cmp .*err" shows many potential
problem spots.

Hmm. Looks like it is only a problem if you are calling a shell function
(since it is the shell function's trace output you are seeing). So this
test would be OK as-is, but testing for an error, like:

  test_must_fail git branch -u foo foo 2>stderr

would not be, because we see the trace from test_must_fail. So some of
the callsites found by my grep are actually probably fine.
