Report of use of "local" per t0000-basic.sh

Hi All,

Based on the note in t0000-basic.sh below, I am just letting you know that I have encountered a lack of support for the "local" on the z/OS 2.3 USS platform except within a function. I thought you might want to know.

There are a other things that do not work, particularly preservation of the value of $? across { } so test_eval_ does not work properly - I had to patch it for the tests to catch non-zero completion codes. I had to move to bash to get much of the test infrastructure. The other item that does not work is the negative lazy prerequisites, so no tests that depend on that.

I am not contemplating submitting any patches for this situation at this time because of other pretty significant encoding issues on the platform, but thought the group might want to know about this.

Cheers, Randall

# This test is an experiment to check whether any Git users are using
# Shells that don't support the "local" keyword. "local" is not
# POSIX-standard, but it is very widely supported by POSIX-compliant
# shells, and if it doesn't cause problems for people, we would like
# to be able to use it in Git code.
#
# For now, this is the only test that requires "local". If your shell
# fails this test, you can ignore the failure, but please report the
# problem to the Git mailing list <git@vger.kernel.org>, as it might
# convince us to continue avoiding the use of "local".
