Uhm, depends what you mean by "best" ;-)
If you wanna lay low and go with the flow then yes, I believe you've got
it right what is current common practice.
...but what I find "best" is slightly different. I would put this as
debian/copyright:
Format:
http://www.debian.org/doc/packaging-manuals/copyright-format/1.0/
Upstream-Name: charsetdetect-ae
Upstream-Contact: Artyom <yom@artyom.me>

License: LGPL-2.1+
Files: debian/*
Copyright: held by the contributors mentioned in debian/changelog
License: LGPL-2.1+
License: LGPL-2.1+
License-Reference: /usr/share/common-licenses/LGPL-2
...and I would then also add this as debian/source/lintian-overrides:
# License is in License-Reference field (see bug#786450)
missing-license-text-in-dep5-copyright
missing-license-paragraph-in-dep5-copyright
I.e. I would...
1) Move the license grant to a custom "License-Grant" field in the
Files paragraph, to machine-readably distinguish between that and
the generic license
2) Skip the part about where generic license can be had as is it a)
irrelevant when we do include it with Debian, b) arguably not part
of what must be included verbatim, and c) old-style postal
address reference where newer boilerplate refer to a URL.
3) Move reference to generic license to custom "License-Reference"
field in the License paragraph, to machine-readably distinguish
that from verbatim copied actual license text.
4) Silence lintian misinterpreting what I did.
Hope that is helpful too (no matter which approach you choose),
- Jonas
