/**
Get the value to display for the bsh interactive prompt.
This command checks for the variable bsh.prompt and uses it if set.
else returns "bsh % "

Remember that you can override bsh commands simply by defining the method
in your namespace. e.g. the following method displays the current working
directory in your prompt:
<p/>
<pre>
String getBshPrompt() {
return bsh.cwd + " % ";
}
</pre>

String getBshPrompt()
{
if ( bsh != void && bsh.prompt != void )
