history clean-up

[joe.chlimoun@l3harris.com]

What's the best way to remove history entries?

Let's say I import a large set of new issues, then realize there was bad data in one field.  I correct the field and reimport just the field on all the issues, but I don't want the history to show a change on the field (since it's not meaningful change, just a typo in my CSV).

I found the changegroup and changeitem tables in the DB... is there a problem with just deleting the relevant entries?  Is there anything else that refers to these tables that would need to be manually cleaned up?  Is there an API to do this that would ensure data integrity?
