there is no line drawn on the ground, you're standing in a line.
I had this argument (and believe I posted here) a few years back with my girlfriend. We got to a point where we contacted someone from Merriam Webster to get an official answer. I'll have to find the email, but it was deemed that either is appropriate, but geographically focused. Areas of the Northeast (including Boston and NY) have adopted the on line usage regardless of whether a line is painted or not. On line, not on-the-line.
