CLI output goes from Left Justified to Right Justified?

What would cause the cli output to go from lining up on the left side to lining up on the right side?
It happens to me alot when running multiple scripts. Sometimes it does it when mafia aborts a script and sometimes in the middle of a script without warning. It generally happens when running a turn burning script. These scripts are just using print() to display items on the page and mafia's cli output messages are also affected.

Biggest culprits are macguffin.ash and autobasement.ash.
Today it happened when macguffin.ash tried to equip a custom outfit that was already equipped. Mafia did not like that...

This seems to happen when a printed line contains a really long sequence of characters with no spaces, which therefore can't be word-broken - that's why forum software such as vBulletin inserts spaces into such lines.

The problem can be fixed, at least temporarily, by clicking on any line of text in the window and dragging to the left.

It also happens (or used to happen, I haven't tested it recently) if you try to equip a custom outfit that you don't currently have all of the pieces to.
