If `/bin/sh` is `dash`, it might not have `set -o pipefail`, which seems
to be a `bash` extension.

I think there's some useful incantation that threads `echo $?` around
through a bunch of file descriptors through several layers of subshells,
though.
e.g.,
{{{
$ ( ( ( (echo foo; echo bar; echo baz; false); echo $? >&6 ) | grep -v bar
>&7 ) 6>&1 | exit `cat` ) 7>&1 || echo fail
foo
baz
fail
}}}
but I'm trying to figure out if there's a simpler way to accomplish that
file descriptor plumbing.
