I initially named it --ignore-non-existent, but I thought the option
was too specific.

--ignore-errors or --treat-errors-as-warnings imply all errors. It
might make sense to always fail at certain errors, like 'mark not
found'. I thought 'relaxed' or 'tolerant' would imply that only some
errors will be allowed, not all.
