==========================================================================
The problem - the English string here updated but there is *no indication*
that this occurred for the translator.

By the way, if I do this:
$ pomerge -t Bundle2.po Bundle.po Bundle3.po

*Now* Bundle3.po contains what I expected Bundle2.po to contain the first time.
