Bug#542747: [frontend] check mismatch between Distribution and Changes in *.changes

[Russ Allbery <rra@debian.org>]

Package: lintian
Version: 2.2.14
Severity: wishlist

While we can't easily check for mismatches between the *.changes file
and the debian/changelog file in the source package, the latter is
copied into *.changes as the Changes field.  We can therefore check
whether the distribution in the first line of the Changes field matches
the Distribution.

I think we only want to do this check if the first line of the Changes
file says UNRELEASED, since there are valid use cases for a mismatch
otherwise.  But in the UNRELEASED case, that means that someone forgot
to update debian/changelog and only modified what went into the
Distribution header, which deserves a tag.
