* Documenting the changes to syslog.filter https://github.com/php/php-src/pull/4265 restored the previous handling of multi-line log messages by adding `syslog.filter=raw`. * Highlight the fact that line splitting is happening in all of the three original modes, but not in "raw". * Add "raw" to syslog section of 7.3 migration guide Closes GH-589.
