Steve, I've just realized that my patch doesn't fix everything.
There's yet another thing which isn't supported by dash: the $LINENO
variable.

What do you want to do: make the hook scripts compatible with both
bash and dash, or force the use of bash. My first patch attempts to
make the scripts compatible with both shells, but that might not be
what you want to do given the restrictions brought by dash.
