Ah yes this was lost when we changed to just use the format aliases
code. Try this diff for now which lets you set a length limit when using
the full format. You'll want to use #{20:pane_title} instead of #20T.

Get your SQL database under version control now!
Version control is standard for application code, but databases havent
caught up. So what steps can you take to put your SQL databases under
version control? Why should you start doing it? Read more to find out.
