I have mistakenly changed the content of some lang strings while fixing bugs recently. This is bad.
The correct procedure is to delete old language string, and create a new one with a new name. That way translators can see the strings that need to be retranslated.
So I need to
1. Get a list of which strings I have changed from CVS.
2. Email firstname.lastname@example.org to explain my mistake, and ask them whether they would prefer me to:
3a. Rename all the changed strings now.
3b. Give the the list of changed strings so that they can retranslate them.
