transposing delimited values using GREP only

 ok so this is silly but I don't care, because as recently as a month ago it was stupid hard, & then *poof* a way to do it popped into my little head.

how to

TRANSPOSE

with nothing but

GREP

PREP:

number rows w/ a tab after the number

format:

<STEP #>

<GREP>
