The first "" are redundant, and you can't be sure whether a space or a
tab appears as the whitespace in the selection pattern.  But how
likely are we to have a shell that has an option that has the substring
"posix", without also supporting the actual option "posix"?  Why not:

case `set -o 2>/dev/null` in
  *posix*) set -o posix ;;
esac
