Bug ? May-be / Maybe not ...
 
Anyway, just let you know:
(1) the split( /\s+/o, 3) does not work as we want.
(2) you could use squeeze, but still have tailling problem ...
(3) Ruby behaviour the way like that now... ( you may need do more work on
the last item. )
 
irb(main):001:0> '    A     50       3 for 130'.split(/\s+/o, 3)
["", "A", "50       3 for 130"]
irb(main):002:0> '    A     50       3 for 130'.squeeze.split(' ', 3)
["A", "50", "3 for 130"]
irb(main):003:0> '    A     50       3 for 130     '.squeeze.split(' ', 3)
["A", "50", "3 for 130 "]
