Subject: Strangeness in Find.find

I was just looking at lib/ruby/1.8/find.rb and I am stumped by the marked
line:

  def find(*paths) # :yield: path
    paths.collect!{|d| d.dup}       # << ?!
    while file = paths.shift
      ... etc

For each element of the 'paths' array, it is duplicating that entry, then
collecting those duplicates into a new array, and then immediately throwing
away that array!

It also exists in 1.6 except the variable is called 'path' not 'paths'

Does this line have a useful side-effect that I can't see? Or was it
intended to be

   paths = paths.collect{|d| d.dup}

Regards,

Brian.
