Looks good, but there was one failure:

  + test xfail = xfail
  ++ env sh -c '\c=d echo fail'
  sh: c=d: command not found
  + test x = xpass
  + fail=1

This is the offending line of tests/misc/env:

    test "x$(env sh -c '\c=d echo fail')" = xpass || fail=1

Compare these:

  $ env sh -c '\c=d echo fail'
  sh: c=d: command not found
  [Exit 127]
  $ env sh -c 'c=d echo fail'
  fail
