[Uhhhhhh] Test, I stumbled onto something completely by accident....

Was messing around with some ascii art in the comments and ended up doing something very......unexpected. Now I'm sure someone well-versed in site design/programming knows exactly what I did. Anyway, input is this:

First Line: |x|y|z|
Second Line: |-

and you get this:

|x|y|z| |-

###Update! Additions:

Third Line: |a|b|c|
Fourth Line: |

and you get this:

|x|y|z| |- |a|b|c| |

Keep going with: |1|2|3| and: |

and you can get this:

|x|y|z| |- |a|b|c| | |1|2|3| | |and|so|on....| |

|Needless to say it was VERY unexpected|also the normal formatting works within the bars too| #Not headers though....| Hmm I wonder| What happens| when you put a lot of boxes in| to the input| Looks like it will expand downward|based on what the columns|are consisting of| So how far can I make| These things go|Maybe I'll break something??| |-

It looks like you can "break" this after enough columns. Above example goes on for a while longer to the right.

So...........essentially.......what in the hell did I just do? And am I supposed to be able to do it?
