[GNC] Add Price Quotes

[Robin Chattopadhyay]

Hi-

Using GC 3.1 with SQLite backend on Linux Mint 18.3...

When running "gnucash --add-price-quotes ~/Documents/file.gnucash", the
prices are loaded but the process doesn't appear to terminate.

The trace file doesn't having anything other than MESSG or INFO entries.

I only notice because I'm getting the lock message when I start gnucash for
regular data entry.

Thoughts on what's going on?

Thanks,
Robin
