No, the #!-header is only information. When you run "make test" we actually invoke the shell ourselves using $SHELL_PATH.

Ah, my fault. I was thinking we overrode $SHELL along with $SHELL_PATH, but we do not.

The correct patch is to stop using $SHELL, but not to switch to a manual /bin/sh. It should use $SHELL_PATH instead, which is how you tell git your path to a sane bourne shell.
