Lintian tag information: debian-watch-file-specifies-old-upstream-version (type: warning)

Description (from lintian-explain-tags)

The watch file specifies an upstream version number which matches the
upstream portion of an old debian/changelog entry, and the current
debian/changelog entry specifies a newer upstream version. The version
number in the watch file is very likely to be incorrect and probably
should be replaced with the current expected upstream version. Otherwise,
DEHS and similar projects will think the package is out of date even when
it may not be.
