Fix typo "reaults" -> "results".
Munge *all* result files in the result directory.

Before, I'd tried to be clever and only pick up the most recent results.
Cleverness doesn't work well for me. On some name collisions valid new
results would create file names with numbers infixed before the .xml.
Picking only the results that didn't have numbers meant missing some
actual results.

I'll just do the simple thing and munge all of the results I find now.
