What did you test?

    >ruby -ve 'p "abc def ghi".split(/(\s+)/)'
    ruby 1.7.2 (2002-05-07) [i386-freebsd]
    ["abc", " ", "def", " ", "ghi"]


Hmm, by the way,

    " abc def ghi ".split(/(\s+)/)

yields

    ["", " ", "abc", " ", "def", " ", "ghi", " "]

what criteria causes asymmetry of prefixing "" and no trailing that?
I forgot the thread on this issue....
