Wait.  After doing this,

    $ mkdir -p src/a && >src/b 2>src/a/c && chmod a-w src/b src/a/c
    $ cp -R src dst
    $ ls -lR dst

dst/b and dst/a/c are 0440 (with umask 0027, which makes src/b and
src/a/c also 0440, which is copied with "cp -R").

I was primarily worried about t/lib-gpg/* being read-only from a
src-tarball extract when we had a discussion that led to e7f224f7
(t/lib-gpg: make gpghome files writable, 2014-10-24).
