In a POSIX compliant system, you should be able to rely on 'sh' being
available in the system PATH (you can't rely on where 'sh' is without
interrogating the system which is hard to do remotely):
http://pubs.opengroup.org/onlinepubs/007904975/utilities/sh.html
Where possible, utilities shouldn't expect a user's interactive shell to be
POSIX compliant, or make any assumptions about a user's shell, so
explicitly invoking 'sh' is much better practice.
Having said that, I can see why some projects may not be particularly
concerned about this.
