Package: lintian Version: 2.5.84 Severity: wishlist I don't know how well this will work or if it will produce false positives, but inspired by having just reported yet another bug about a package whose short description contained the start of a sentence that continued into the long description, I wonder if Lintian could try to detect that somehow.
One possibility would be to check for a long description that starts with a lowercase letter, other than the case where the long description starts with the package name or a word from the package name. That *might* still produce some false positives, though. If that still produces too many false positives, perhaps it would work to check for a short description that looks like a sentence followed by more words, and *then* a lowercase word starting the description. For instance: Description: words words words. Words words words words words. Words words words.
