Bug #1693: ARGF.rewind Doesn't Reset ARGF.lineno
http://redmine.ruby-lang.org/issues/show/1693

Author: Run Paint Run Run
Status: Open, Priority: Low
ruby -v: ruby 1.9.2dev (2009-06-25 trunk 23854) [i686-linux]

ARGF.rewind doesn't reset the current line number to 0. IO#rewind does. 
This happens on all Ruby versions I have installed locally.

    $ ruby -ve 'p ARGF.lineno; ARGF.readline; ARGF.rewind; p 
ARGF.lineno' /etc/passwd

This seems to be resolved on 1.9 now; 1.8 is still affected.
