Concise.pm: extract padname code and fixup split

The code that prints '$i:1,2'' in something like 'padsv[$i:1,2]':
extract it out into a separate function, then use it with  split
to display the array name rather than just a target number in:

    $ perl -MO=Concise -e'my @a = split()'
    ...
    split(/" "/ => @a:1,2)[t2] vK/LVINTRO,RTIME,ASSIGN,LEX,IMPLIM ->6
