Bug#981767: adequate: ambiguous report of obsolete-conffile leads to false-positive bug reporting

[Thorsten Glaser <tg@mirbsd.de>]

Package: adequate
Version: 0.15.3
Severity: normal
X-Debbugs-Cc: tg@mirbsd.de

Adequate reports obsolete-conffile if a package no longer ships a
conffile, but there are two cases to distinguish:

• the package’s buggy and didn’t clean up
• dpkg didn’t remove the conffile because it was locally changed

Only the first one should result in a bugreport to the maintainer
of the package. Can you please distinguish these somehow?

Thanks!
