Oh, I misunderstood the email.
Indeed the, there is --env-shebang option, but it's not a default one,
and it does break binaries,
installed under JRuby.
Yes, it would be nice to have a way to make --env-shebang the default
one without patching the rubygems sources.

I think this was fixed. At least when I try to install, say, rake and
provide --env-shebang option,
I end up with rake script with proper shebang: #!/usr/bin/env jruby
