This is probably something for the gcc-rust maintainers to review
(rather than me self-reviewing with my "diagnostics maintainer" hat
on).

Doesn't have a ChangeLog entry, FWIW.
Doesn't have a signed-off-by, so here's one:

"error_at"...

... to match this call.

Otherwise, LGTM, but as I said, this is more in the gcc-rust
maintainers' area.
