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 translation@moodle.org to explain my mistake, and ask them whether they would prefer me to:

3a. Rename all the changed strings now.

or

3b. Give the the list of changed strings so that they can retranslate them.
