if dash is given an option to `set -o` that it doesnt understand, it aborts the script instead of simply having `set` exit with a non-zero value

this causes `ldd` to fail with dash

this script should show "moocow" but only gets out "moo" with dash:
#!/bin/dash
echo -n moo
set -o pipefail 2> /dev/null
echo cow

This is not a bug in dash; susv3 explicitly allows this behaviour. See 2.14 "Special Built-In Utilities", item 1: "A syntax error in a special built-in utility may cause a shell executing that utility to abort, while a     syntax error in a regular built-in utility shall not cause a shell executing that utility to abort." set is a "special built-in utility".
