That one seems really safe to me.

Testing it requires me to sit down for on or two hours, ignore all
other stuff and work on this....this may take time.

I agree that populating all Last-Translator fiels with the last
translator/committer is quite useless. After all, we all know that the
important information is in the master file.

Hmm, that snipped is more difficult for me to detail but I see the
point and I'm confident in your shell writing skills (more than mine
anyway) so I'll test it as is....

So, if we want this tested (and we do), this won't probably happen
very soon.....I just leave your mail in my Inbox as a reminder (my
Inbox is my usual TODO list).
