Local execution on some variant of Debian testing.

The tests that fail are t0610.29 and t0610.30, both of which are
"honors core.sharedRepository" with umask 002 and umask 022.
They expect "-rw-rw-r--", but actually get "-rw-rw----" when
the user's umask is 077 (or 007 for that matter).

If you add "umask 002" or "umask 022" near the beginning of the
script (e.g. before including test-lib.sh), the tests pass even when
the user's umask is 077 or 007 when the tests are run, of course, so
there is something the test must be doing in the test repository
before it forces the umask to 002/022.
