Bug #4294: IO.popen ['"ping"', 'localhost -n 3'] fails
http://redmine.ruby-lang.org/issues/show/4294

Author: red stun
Status: Open, Priority: Normal
Category: core, Target version: 1.9.2
ruby -v: ruby 1.9.2p136 (2010-12-25) [i386-mingw32]

>> RUBY_VERSION

>> IO.popen ['"ping"', 'localhost -n 3']
Errno::EINVAL: Invalid argument - "ping"
        from (irb):6:in `popen'
        from (irb):6
        from d:/sdks/ruby/ruby-1.9.2-p0-i386-mingw32/bin/irb:12:in `<main=

tested on both ruby-1.9.2-p0 and ruby-1.9.2-p136

it works if the extra double quotes around 'ping' are removed.
