Actually I think this was the case for web-mode given Thomas' response
in [1].  Also, when I asked in #debian-mentors, more people share the
same view and they also choose not to add a separate license clause for
"File: debian/*" as a result.  I think that suggests that omitting it
may be a common practice, and if that is common enough, it could be
considered intentional.

Still, I think it would be good to have a policy or recommendation on
how a DD or DM should do here.  I don't see this addressed in the Debian
Policy or the Debian Developer Manual though.
