:-). Very nice.

I took a look at this and [1], and I agree that 3/3 is probably better
applied after [1], since it doesn't leave any gap between the existing
behavior of ">$@+ && mv $@+ $@" and ">$@" with .DELETE_ON_ERROR.

But I don't feel strongly about the order in which the two are applied.
Your 3/3 without [1] isn't wrong, it just leaves us the opportunity to
permanently leave around a broken tags file permanently, whereas having
[1] applied ahead of time means that the broken tags file is only
visible racily.

I reviewed these patches carefully, and they look good to me. I'm
delighted that `make tags` is no longer PHONY.
