Cannot run scripts in classpath (but not on filesystem) without using -r and a false -e argument

Since a recent update, using the -r command line switch to require a file will block waiting for input from the console. This appears to be the correct behaviour.

Since this is now happening, the -r switch can no longer be used to run a script from the classpath, unless a 'fake' -e switch is used.

A possible solution would be for jruby to also search for the initial script in the classpath, instead of only looking in the filesystem.
