Issue #8: no newline at end of file.

Not sure if it is in the C++ standard, or was, but apparently some
compilers may complain when files don't end with a newline (though
neither GCC nor Clang as our CI and my local builds are fine).

So here are all our generated source which didn't have such ending
newline (hopefully I forgot none). I just loaded them in my vim editor,
and resaved them. This was enough to add an ending newline.
