Noise in comments added to bugtrackers

Every time someone update filter or issue cibuglog adds comment to bugtracker. It would be all good but sometimes these filters are updated frequently and markdown_diff between new and old filter is really long (like 6k characters) and not useful.

What option would be the best to implement?

• Some on/off flag in settings, eg: MINIMAL_COMMENTS = True or COMMENT_MARKDOWN_DIFF = False
• Removing these diffs altogether
• Any other idea?
