You should add 'disabler: true' to the git find_program in Meson. If Git
doesn't exist on the system with the way your patch is currently
written, the targets would be defined, even though they would never
succeed.

You may also want to make sure that we are actually in a Git repository.
I don't think git-archive works outside one.

Re the autoclrf, is this something we could throw in a .gitattributes
files?

I would suggest poisoning `meson dist` in the following way:

if not meson.is_subproject()
    # Maybe edit the comment...Maybe tell perl to print this message
    # instead and then exit non-zero?
    #
    # Meson has its own distribution building command (meson dist), but we
    # are not using that at this point.  The main problem is that the way
    # they have implemented it, it is not deterministic in the above sense.
    # Also, we want a "make" version for the time being.  But the target
    # name "dist" in meson is reserved for that reason, so we call the
    # custom target "pgdist" (so call something like "meson compile -C build
    # pgdist").
    #
    # We don't poison the dist if we are a subproject because it is
    # possible that the parent project may want to create a dist using
    # the builtin Meson method.
    meson.add_dist_script(perl, '-e', 'exit 1')
endif

0002 looks pretty reasonable to me.

0003 works for me :).
