As of now it seems that this has been fixed sometime before commit https://github.com/logstash-plugins/logstash-codec-multiline/commit/65345f8d16851a0127bcfd5ef28369ce01350cdf but the changes are not reflected in production.

input {
    stdin {
        codec => multiline {
          pattern => "^\s"
          what => "previous"
        }
    }
}
