 I have a MacRuby Cocoa app named FooBar, but I cannot pass any arguments
 to the program:

 {{{
 ./build/Debug/FooBar.app/Contents/MacOS/FooBar 0
 }}}

 I get:

 {{{
 No such file or directory -- 0 (LoadError)
 }}}

 It turns out that macruby_main() transforms the argv array incorrectly. At
 this time it transforms the original argv into something like this:

 {{{
 argv[0 .. argc - 1] = original argv values
 argv[argc + 0] = -I/path-to-app-dir/(...)/Resources
 argv[argc + 1] = main .rb file
 }}}

 This causes any command line arguments to be recognized as interpreter
 arguments, not app arguments. The attached patch changes the
 transformation into something like this:

 {{{
 argv[0] = original value
 argv[1] = -I/path-to-app-dir/(...)/Resources
 argv[2] = main .rb file
 argv[3 .. N] = rest of original argv
 }}}
