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

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.
