There was in issue in all the experimental version which failed to load
the documentation via the help command in the pdl shell. I've pushed a
patch for that in git, I don't think I'll upload ~ex4 and just include
it in next weeks upload to unstable.

After uploading pdl (1:2.016-1) to unstable, I'll also rebuild all
reverse dependencies with it and upload them to unstable too.

I'll send a separate mail about the pdl transition later.
