Allow selection of which shell the tests run under
The default shell in cram is /bin/sh but for our purposes we have a lot of cases where it is more convenient to use bash syntax. It would be great if the shell cram ran tests under was selectable.
I've implemented the enhancement as a patch at https://bitbucket.org/kisielk/cram-mq/src/tip/shell
Please have a look and let me know what you think.
