Command-line is sensitive to argument order

[Jesper Öqvist]

The support for separate options and option values makes the command-line sensitive to the order of arguments. This can be problematic for options which have optional arguments such as --rewrite. For example:

java -jar jastadd2.jar --rewrite foo

fails, but

java -jar jastadd2.jar foo --rewrite

passes.
