^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
This only tweaks bash's behavior where it otherwise differs from
POSIX. It does not disable the myriad extensions.
There is a tool ShellCheck that among other things can be used to
warn about unportable code in shell scripts.
https://www.shellcheck.net/
I haven't used it myself yet. It is written in Haskell, so it
suffers itself from portability concerns.
