Bug#890920: lintian should warn about very short changelog entries

[Adrian Bunk <bunk@debian.org>]

Package: lintian
Version: 2.5.75
Severity: normal

lintian should warn if the changelog for the current
version contains a very short (< 10 characters?) entry.

Example from a recent upload:

  * dh 11
  * R³


Suggested tag description:

debian/changelog for the current version contains
a very short entry.

This makes it usually harder to read the changelog.
Often the problem is excessive use of abbreviations.

Keep in mind that:
* Many users will read the changelog through apt-listchanges.
* The information in debian/changelog is permanent.
  It is not uncommon that people read changelog entries
  that are more than a decade old for understanding why
  a package works in a specific way.

Example for too short entries:
  * dh 11
  * R³

Suggestion how to improve this example:
  * Switch to debhelper compat 11.
  * Rules-Requires-Root: no
