[Haddock] ghc-7.6.2 breaks haddock interface...

good point; let me add a bit of information about the Debian
infrastructure: There are two ways of rebuilding stuff. Regular uploads
and binNMUs.

Regular uploads require manual work: Adding a changelog entry to the
source file, building it locally (which is required and means that the
developer has to make sure he builds everything in the right order, and
that he has to install previously built packages), signing the package
and then uploading the new source package together with the built
package. Tedious work.

binNMUs can be scheduled programatically and cause the Debian
autobuilder infrastructure to built the package again on the selected
architectures (possibily all). The infrastructure is smart enough to
figure out the build order itself and no further interaction is
required. Nice.

Unfortunately, the latter can only rebuild arch-dependent packages,
which in the context of Debian packages means -dev and -prof.
Architecture independent packages (here: -doc) cannot be built this way
and thus can only be rebuilt by full sourceful uploads.

The .hi files reside in the arch-dependent packages, while the .haddock
files don’t.


I know that you might think now: Well, then fix your infrastructure. A
valid point. But I am not in the position to do so, hence my hope for
only as many haddock interface number bumps as required. (The Debian
side thinks things about Haskell like: Well, get your ABIs stable so
that we can bugfix individual packages without breaking other
packages...)

Greetings,
Joachim
