  remove svn:executable from scripts without a shebang line
........

Run 2to3 over the Demo/ directory to shut up parse errors from 2to3 about lingering print statements.

Cleaned up existing code by abstracting code to parse arguments.  Also removed
any unneeded operations (such as calling 'int' on a division when using floor
division also works).  Fixed a bug where the values  returned by
OldStyleRange could be short by one value.  Added more documentation.

Testing code also has a basic sanity check.

From SF patch #852334.

Run these demo scripts through reindent.py to give them 4-space indents.  I've verified that their output is unchanged.
