Actually, this mode doesn't disallow bashism, it modify some minor
 behaviour of bash.

I also remember when I was a TU padawan, a jedi master, ask me to avoid
bashism in install scripts because /bin/sh can be modified by user to
something else and we should be posix as possible. I never checked that
before but we have currently at minimum 50 install scripts with bashism.

I will be more relax writing my install scripts :)
Thanks for clarification.
