backticks launching vi causes unexpected issues in vi
-----------------------------------------------------

                 Key: JRUBY-2049
                 URL: http://jira.codehaus.org/browse/JRUBY-2049
             Project: JRuby
          Issue Type: Bug
          Components: Core Classes/Modules
    Affects Versions: JRuby 1.1RC1
         Environment: OS X 10.5
            Reporter: giles bowkett


If you do this:

gem install utility_belt

and then enter regular IRB and do this:

vi

you should then be able to enter arbitrary code in vi, which then executes 
(after you close the file) in the IRB session you were in.

however, if you do it from jirb, the vi which is launched has this weird 
inability to perceive the escape key.

utility belt also has similar shortcuts for emacs and TextMate. on my system 
TextMate behaves as expected, but emacs fails to launch at all.

in #jruby headius noted this is probably related to an issue with readline.
