[PATCH 0/1] Fix broken test with zsh as /bin/sh

["brian m. carlson" <sandals@crustytoothpaste.net>]

macOS Catalina provides zsh as one of the three options for /bin/sh (the
other two being bash and dash).  Therefore, it's possible that people
will use zsh as /bin/sh and expect it to work when running Git and the
testsuite.

There are two things required for this to happen.  One is a patch to zsh
to make it run all items in a pipeline in a subshell in sh mode, just as
POSIX requires.  I've sent a patch[0] upstream to make that happen;
without that patch, multiple tests fail.

The other is this patch, which addresses a difference in behavior
between bash and dash, which strip out NUL bytes from the output of a
command substitution, and zsh, which does not.  Both behaviors are
permitted by POSIX, so this patch makes the test work in either case.
