Filtering system logs doesn't include all log entries
Log entries to be included in the filtering is capped/restricted to the most recent 5000 entries. So log entries that match the filter that are older than the most recent 5000 are not included.
Lasse proposed a couple solutions:
I refined it just a tad. Same method of fix. Implementation just altered slightly.
Needs review though to make sure increasing the potential size of the storage variable won't be a problem. Shouldn't really have an impact on systems with default log size, as the 5000 should have pretty much covered all that anyway.
