Would you mind going to third_party/devscripts/licensecheck.py line ~488 and
make it match the new license header instead?

Err, licensecheck.pl. Hope your Perl is not too rusty.

Like this?

The old URL still might be used elsewhere in the source tree (according to
codesearch.chromium.org), but that’s OK, because the new pattern will match both
the old and new URLs.
