Ah yes. When I first wrote the code, the log file wasn't HTML format, 
but used ^ as a delimiter for some markup, so I escaped that character 
so that log data wouldn't corrupt the file format. When I switched to 
HTML, I forgot to remove that character from the escape list. I'll fold 
the fix into v4.
