Hey Simon,

this has been stuck for a while, so let's see how we can get at least
some of this working.

I recently refactored the test metadata parsing to be more easily
extensible (as I added support for Ubuntu's click packages). During
that course, the internal "test" representation can now hold either a
path to an executable (as it always has) or a shell command. This
isn't exposed yet for debian/tests/control, but it would be fairly
simple now to write the above as

  Test-Command: <piece of shell>

so you can put any adverbs or other wrappers directly into the control
file. We could support multiple Test-Command: lines in each paragraph
so that you can still have a common Restrictions:/Depends etc, and of
course being a shell command you can use globbing, `find`, etc.

This has an obvious semantics, and with a shell command you should be
able to do pretty much anything. Does that suit your needs?

If we actually need this, it's not too hard to implement now, but I
wonder if there's a real-world use case for this already?

Likewise, it's now rather easy to implement, and perhaps even better
than "Tests: <" from above?
