[Mediawiki-l] user_groups cleanup

[Frederich, Eric P21322]

Hello,

In playing around with the Lockdown extension I was creating some new
groups and found that the ug_group field in the user_groups table can
only be 16 characters long.

After figuring this out and changing my group name to something shorter,
I noticed that I still had the truncated group names in the user_groups
table.

Are these safe to delete manually?

Is there a better way to clean this stuff up?

Thanks,
~Eric
