... now using
JRuby::Util.load_ext
mechanism for #5205contains a couple of interesting features/fixes - wonder why it lagged behind
e.g. OSv support, HP-UX working, avoided (class) memory leaks, printing "Display all 104 possibilities? (y or n)" on a new line, ...
UPDATE: there seems to be one visible regression under Linux - printing space after irb completion
believe we can fix that and also make jruby-readline usable as a standalone gem
... should we eventually also push to RubyGems? (would be great to test out new release under Windows)
