This is important, because it affects the ordering of entries in .pot and
.po files. Most existing files are in alphabetic order already, so this

It must not be included in translations, because it contains files for
tests and/or for future development (mainly new Eeschema lib code) and
are therefore not used actively in Kicad code.
