In which directory?

    $ make -C t test-lint-shell-syntax
    ... passes silently ...
    $ ed t/t0000-basic.sh
    /test_expect_success/
    a
            which sh
    .
    w
    q
    $ make -C t test-lint-shell-syntax
    t0000-basic.sh:28: error: which is not portable (please use type):      which sh
    make: *** [test-lint-shell-syntax] Error 1

If you edit out '@' (but nothing else) from this line:

> 	@'$(PERL_PATH_SQ)' check-non-portable-shell.pl $(T)

and run the above again, you would see that it is running this shell
command:

'/usr/bin/perl' check-non-portable-shell.pl t0000-basic.sh t0001-init.sh ...

If you introduce a Perl syntax error to check-non-portable-shell.pl,
like this, you will get:

    $ make -C t test-lint-shell-syntax
    syntax error at check-non-portable-shell.pl line 11, near "whoa

So... is your shell broken?  The above seems to work for dash, bash,
ksh and zsh.
