Title: Fix for irb crash during completion

For some Ruby implementations Readline.point is missing. This causes irb to
crash under Ruby Enterprise Edition 2011.12 for any irb completion that is
attempted. This change at least avoids the crash though the original function
(opening the text editor) cannot be executed anymore.
