Livecode performance problem

[Alex Tweedly]

I can't answer for anyone else, but for me - because I never thought 
about it :-)

Combine by column - never used it before, so never thought of it.

It's significantly faster, roughly 40% improvement over the previous best.

Note, the spec requires that each line begins with the line number, so 
you need to add something like:

>    local tmp

>       put i &CR after tmp
>    end repeat
>    put tmp into x[1]
>
>    put g1 into x[2]
>    put g2 into x[3]
>    put g3 into x[4]
>    put g4 into x[5]
and finish off with

    combine x by column
    put cr after x

to fully match the earlier results.
