#21 Confusion about whether set -o emacs is or is not a bashism
checkbashisms does not treat set -o emacs as a bashism. However, I do not see a corresponding entry in the POSIX sh documentation.

Should checkbashisms start reporting this as a bashism?
Additionally, ShellCheck notes that
set -o emacsis a bashism. checkbashisms should follow suit.
