(One thing more)...

If it's returning 1 perhaps it is not respecting the anchor (^) for
begining and making the match against the second (1-indexed) character
("BCDE"). (So, perhaps it's not the "max quantifier" as on the post
subject).

# without the anchor... ("^")
match = /[A-Z]{1,4}[0-9]{1,4}$/.match "ABCDE1234" => #<MatchData "BCDE1234">

Could you please run the script on the gist to see what it is
capturing? ( https://gist.github.com/1650955 )
