Re: [PATCH] t6030: use $SHELL_PATH to invoke user's preferred shell instead of bare sh

Hmm, shouldn't we also be quoting '$' in front of SHELL_PATH to make the
test_expect_success interpolate the value of SHELL_PATH, instead of hoping
that SHELL_PATH does not have double-quote in it when the shell that forms
parameters given to test_expect_success interpolates it?

By doing this silly thing:

	$ mkdir '/var/tmp/a"b c/'
        $ ln -s /bin/sh '/var/tmp/a"b c/shell'

and then adding

	SHELL_PATH='/var/tmp/a"b c/shell'

after we source "test-lib.sh" in t6030, I see this breaks when the shell
parses to figure out what parameters to call test_expect_success with.
