[TODO] Systematically compare functionalities -- system-installed `magick` vs. AppImage-d `magick`

[KurtPfeifle]

Do the following:

1. Using self-installed /usr/local/bin/magick, run:

   for i in $(magick -list list) ; do
       magick -list $i > magick-system-${i}.list
   done

2. Do the same for ImageMagick-xperimental-x86_64.AppImage. Run:

   for i in $(ImageMagick-xperimental-x86_64.AppImage -list list) ; do
       ImageMagick-xperimental-x86_64.AppImage -list $i > magick-AppImage-${i}.list
   done

3. Then compare results:

   for i in magick-system-*.list; do
       sdiff -sbB -w 240 ${i} ${i/system/AppImage}
   done

4. Evaluate. Draw conclusions. Fix what needs to be fixed.

Observations:

1. Minor differences with:

   configure
   delegate
   font
   log
   mime

2. Major differences with:

   format
   locale
   module

The last test build does not show this behavior any more. I tend to think that the Travis environment currently has hickups... (Because I saw, for a few builds already, all "green" sub-commands with exit codes 0, but the final message nevertheless was and still IS: "Done. Your build exited with 1."

There are only differences left when running ./im.ai -list module...
