Comment 2 for bug 2067490

The best way to describe it, is that it's like when you cat a file without propper formatting and the command output pushes the prompt to the right. This causes a mismatch between where the cursor is shown and where it actually is.

Either way, the issue is more with why it's showing an elapsed time for the last command, which is a change from how the byobu prompts has worked to date.
