bug#21399: Emacs: Guix Package Info omits some inputs

[Ludovic Courtès]

Hello,

For ‘r’, the *Guix Package Info* buffer omits IcedTea from the set of
inputs.  It shows this:

--8<---------------cut here---------------start------------->8---
Inputs            : openblas-0.2.14, cairo-1.14.2, gfortran-4.9.3, icu4c-55.1,
                    lapack-3.5.0, libjpeg-9a, libpng-1.5.21, libtiff-4.0.3,
                    libxt-1.1.4, pcre-8.37, readline-6.3, zlib-1.2.7
--8<---------------cut here---------------end--------------->8---

whereas the recipe has this:

--8<---------------cut here---------------start------------->8---
    (inputs
     `(("openblas" ,openblas)
       ("cairo" ,cairo)
       ("gfortran" ,gfortran)
       ("icu4c" ,icu4c)
       ("icedtea6" ,icedtea6 "jdk")
       ("lapack" ,lapack)
       ("libjpeg" ,libjpeg)
       ("libpng" ,libpng)
       ("libtiff" ,libtiff)
       ("libxt" ,libxt)
       ("pcre" ,pcre)
       ("readline" ,readline)
       ("zlib" ,zlib)))
--8<---------------cut here---------------end--------------->8---

My guess is that somewhere, the triplet for IcedTea is silently filtered
out.

Thanks,
Ludo’.
