Hmm...  lz4 files.  I guess I slept through that transition.  However
my Sid machine still has Sources files without the .lz4, even though
other files have it.

Try this:

    apt-get install lz4

    dpkg -L lz4 | grep bin/
    /usr/bin/lz4
    /usr/bin/lz4c
    /usr/bin/lz4cat
    /usr/bin/unlz4

    lz4cat /var/lib/apt/lists/proxy.pri:9999_debian_dists_stretch_main_source_Sources.lz4q | less

That should at least make the files text again.  Which means I think
following this should work.  But note that I had to test with the
non-lz4 version on my system.

    lz4cat /var/lib/apt/lists/*Sources.lz4 | grep-dctrl -s Package -F Build-Depends,Build-Depends-Indep quilt

Maybe?
