[GNC] Zero price entries

[Fred Tydeman]

Is there an easy way to find all the zero price entries in the price
history?

I have several hundred stock and currency items, some with zero price
entries.

I am used to using Enter (instead of Tab) as a way to advance to the next
field in a new transaction.  Because of that, I believe that caused zero
price entries to end up in the price history.  I would like to find those
zero price entries and delete them.
