Fix right padding when row too long

[AydinHassan]

This PR fixes the negative right padding when the row is too long. We have a few options to improve this:

1. Leave it as it is now where the text goes off the edge:

2. split the row and put it on a new line

3. throw an exception

What does everyone think? @Lynesth @mikeerickson

I'd leave it with the text going off the edge for multiple reasons:

1. It shouldn't happen that much.
2. Breaking the word has to be done correctly, and that depends on language (english, spanish, etc) used and such. Too much work.
3. Throwing an exception is a bit too much. The whole thing is still usable, just a little less beautilful.
