[daip] bk151 (fwd)

[Yuri Y. Kovalev]

Dear colleagues,

For some reason Lorant did not forward it himself, so I am doing it.

I would suggest to comment directly in help to the task uvflg that in 
order UFLG to work one has to put an exactly the same REASON as the one 
used for an original flagging record to be unflagged.

Thanks,
Yuri
