Thanks for taking a look at this, Ludovic.

It is also my understanding that this is based off GNU Bash 3.2. I'd be
hard-pressed to point at any particular changes and call them significant, but
there are a lot of small edge cases that add up, e.g. the special cases around
non-zero returns and set -e are pretty different.

This patch is part of a larger project of mine to get Apple utils packaged up.
It's super useful to have them as a test target for shell script portability in
CIs and the like.
