Fix 2935444 - Sisc wrapper script breaks spaces.

The attached patch is a bug fix for #2935444.

Bundled sisc.shp not found

2004-12-16T01:00:32Z

You bundle the sisc.shp into the sisc.jar but then no
one bothers to search for it if the user doesn't
specify a heap.

This patch corrects that.

maven in 1.9.5 not correct

2004-12-16T00:58:50Z

I was glad to see the maven descriptors in 1.9.5 source
package, but sad to see that they were incorrect.

I repaired them; please find attached the patch against
1.9.5 to straighten things out.

NOTE: Maven _hates_ to have JUnit tests intermixed with
normal sources, and I didn't want to use a patch to
reorganize your source tree. Also, declaring junit as a
dependency is not correct; your PROJECT doesn't depend
on JUnit, only your build does - and maven includes the
correct dependencies for that via the maven-test-plugin.

Method to abort evaluation

2002-07-13T02:03:33Z

Running SISC from the command-line, the user can
abort an infinite loop by hitting Control-C and killing the
Java VM.

When run as an applet by the Java Plug-in, killing the
VM requires quitting the browser and closing everything
down with it.

The attached patch adds an abortEvaluation() method to
Interpreter. AppEval.eval() checks whether this has
been called and throws an "Aborted evaluation" error if
so.

Disallow redefining reserved symbols

2002-07-11T00:40:04Z

R5RS explicitly states that statements such as "(define
define 3)" are not allowed.

This patch updates the DefineEval and FreeSetEval to
catch these illegal statements. It also adds entries to
Util and SISC.properties for the error messages. I also
added a class ReservedSymbols as a lookup. This
functionality may fit better somewhere else, but I tried to
modify the existing code as little as possible.
