Bug#512265: #512265: clarifying the intent of the bug report

[Andrius Merkys <merkys@debian.org>]

Hi Felix,

I noticed you changed the title of the bug report from "lintian: Warn if
a test suite exists but is not run" to "lintian: Warn about unused
autopkgtests", and I doubt this reflects the original intent of this bug
report.

I read the initial Raphael's message as asking to detect test suites not
run at the build time (as per the subject of the message). Not run
autopkgtests are not less important, but this is a separate topic. I
suggest splitting this bug report into two:

* lintian: Warn about unused autopkgtests
* lintian: Warn about unused build time tests

What do you think?

Best wishes,
Andrius
