I fixed the \"error\" where it split the lines incorrectly.

The not including doubble chars was something I wanted, so thats why :P.

(And I know about that $regsubex thingy :P)
But mine is faster:
Regsubex (Yours): 1735
Regular (Mine): 937

Tested with:

//var %x = 10000, %y = $ticks | while (%x) { noop $_split(hi) | dec %x } | echo -a Regsubex: $calc($ticks - %y)

(Change the alias to $split.text to see mine)

So there you go :P
