[darcs-devel] [patch1661] give FileUUID some love

Yes, ppShow is the only import, it contains the main functionality of
the package. It's an extremely useful one if you want to actually be
able to read (as in "understand") some data that is shown to you, for
instance in a failing test. I was planning to use it in other places in
the test suite and in error messages. We also have a number of Show
instances that have been hand-written to give more human-readable output
(e.g. Patchinfo) and it would be much nicer if we could derive all the
instances and use ppShow for display.

What kind of trouble does it cause you? I have installed ghc-8.0.2 and
could successfully build with cabal-2.1.0.0 (cabal new-build as well as
cabal install --only-dependencies, then cabal build; for the latter I
had to install happy from my distro).

Would it be possible to ask the maintainers or the hackage trustees to
adapt dependencies if your problem persists?

If nothing else helps I can remove the dependency.
