Is it just me who finds the above unreadable blob of black ink?
06cbe85 (Make core.sharedRepository more generic, 2008-04-16)
broke the traditional setting core.sharedRepository to true,
which was to make the repository group writable.
The call to adjust_shared_perm() should only loosen the
permission. If the user has umask 002 (or 022) that allow others
to read, the resulting files should be made readable and writable
by group, without restricting the readability by others.

I do not think this gripe after the semicolon belongs before the
three-dash lines.

Hmm, I am very puzzled.
I am afraid I have to ask you for another round. I applied only your
update to t/t1301 without the change to path.c, and the test passes, which
means either (1) the test is incorrect and does not exposing the breakage,
or (2) the breakage is not real and existing code is correct.
