bug#8893: [PATCH 1/2] tests: make test runner a script, not a shell function

[Jim Meyering]

Thank you!
That patch looks fine modulo two typos.
I'm folding in these corrections and have adjusted the
grammar in the commit log (included below).

    tests: make test runner a script, not a shell function

    This change implements a more correct and idiomatic use of the
    features of the Automake-provided 'parallel-tests' harness.
    Moreover, this change is required in order for the testsuite to
    continue to work with the new testsuite harness that is planned
    to be introduced in Automake 1.12 (which, as of the writing date,
    is still under development and in alpha state).

    * tests/shell-or-perl: New auxiliary script.
    * tests/Makefile.am (EXTRA_DIST): Distribute it.
    * tests/check.mk (TESTS_ENVIRONMENT): Remove definition of the
    `shell_or_perl_' shell function, whose code has been moved in
    the new script above (with a few improvements and extensions).
    Do not use it to run the test scripts.
    (LOG_COMPILER): New, properly invoking `shell-or-perl'.
