Alexandros,

Thanks for these patches.  I think your MUA might have mangled these
patches somehow, as many of them are "corrupt" according to git.  Can
you try to resend these?  I'll comment on the patches individually
meanwhile.

I don't think this is needed?

I don't know anything about LV2 and sord, are these inputs really only
used for the build process itself?  :-)

Two spaces after periods, as per 'guix lint'.
