[Pkg-haskell-maintainers] Bug#767762: ghc-mod still contains emacs dependencies

[Michael Alan Dorman]

Package: ghc-mod
Version: 5.2.1.1-2
Followup-For: Bug #767762

Dear Maintainer,

I believe the split between ghc-mod and ghc-mod-el is incomplete, and
can, in fact, lead to a broken package.

As you can see, ghc-mod still depende on emacsen-common, which isn't a
huge dependency, but should be unnecessary.

    mdorman at ogg:~$ aptitude show ghc-mod
    Package: ghc-mod
    State: installed
    Automatically installed: yes
    Version: 5.2.1.1-2
    Priority: extra
    Section: haskell
    Maintainer: Debian Haskell Group <pkg-haskell-maintainers at lists.alioth.debian.org>
    Architecture: i386
    Uncompressed Size: 65.9 M
    Depends: libc6 (>= 2.11), libffi6 (>= 3.0.4), libgmp10, ghc (>= 7.6.3), ghc (< 7.6.3+), emacsen-common (>= 2.0.8)
    Recommends: ghc-mod-el (>= 5.2.1.1-1)
    Description: Happy Haskell programming
     This package provides the executables ghc-mod and ghc-modi. The GNU Emacs integration code is provided by a separate package, namely ghc-mod-el.
     Homepage: http://www.mew.org/~kazu/proj/ghc-mod/

Further and I believe this is where the breakage exists, it still
contains the emacs site-start file:

    mdorman at ogg:~$ cat /var/lib/dpkg/info/ghc-mod.list
    /.
    /usr
    /usr/share
    /usr/share/doc
    /usr/share/doc/ghc-mod
    /usr/share/doc/ghc-mod/changelog.Debian.gz
    /usr/share/doc/ghc-mod/changelog.gz
    /usr/share/doc/ghc-mod/copyright
    /usr/share/doc/ghc-mod/buildinfo_i386.gz
    /usr/bin
    /usr/bin/ghc-modi
    /usr/bin/ghc-mod
    /etc/emacs/site-start.d/51ghc-mod.el

Based on the code in that file, if someone has haskell-mode installed,
but does not have ghc-mod-el installed, they will get an error when
entering haskell mode as emacs tries to call a function that does not
exist.

I think the simple solution is to move both the emacsen-common
dependency and the site-start.d file into ghc-mod-el, where I believe
they belong.
