They do go into the libghc-hlint-dev package, not sure what you are 
hinting at here:

The test can be abstracted, but not the flag, as that is (unfortunately)

I think these two cases can go (or rather, stay) in
debian/hlint.install, while the rest looks like it can go into

There are only those two lines in the threadscope.install; I guess you
mean that the install/$(CABAL_PACKAGE) target in the makefile can be
