allow GSH to support newlines

Maybe I'm doing it wrong, but I see the need to write some gsh scripts with loops and conditionals. Collapsing them into one line really hurts maintainability.

It would be very useful if gsh was BeanShell + Grouper (looks like that's the design intent of BeanShell.) http://www.beanshell.org/

I'm sure you are right. GSH doesn't have any parsing capability of its own -it just passes each line to bean shell - so, in order not to break what is there, we would have to introduce additional syntax to allow multi-line commands e.g. use a \ at the end of any line that continues, build up the string and pass to bean shell when we get a line not ending with \
