Re: [PATCH] diff: "S_IFREG | 0644" to "(S_IFREG | 0644)" to avoid warning

But tests on NetBSD with /bin/sh still fail since we use cd -P, but we
have unapplied patches for that so I didn't pursue it:

Aren't these v1.7.0-rc0~76^2 and v1.7.0-rc0~76^2^?

Here's a patch for the more important of the remaining problems.  I'm
just guessing here; untested, of course.

Subject: tests: use pwd -P to simulate cd -P for portability

NetBSD supports pwd -P but not cd -P.  POSIX has required both for
a while, so this should not be an issue for most Unix-like platforms.

The test harness uses cd -P to ensure $PWD and $(pwd) agree;
cd $(pwd -P) should do that, too.

If pwd -P fails on some platform, with this patch, the test harness
will die with 'FATAL: Unexpected exit with code 1'.
