--- Comment #12 from Kyle Auble kauble@lavabit.com 2013-08-04 22:55:12 CDT --- I can confirm this (using Firefox 22 on Ubuntu 12.04). After fiddling with the editor a little on the WikiSandBox, it's specifically a problem in the GUI editor so as long as you stick to the text editor you'll be OK.
It looks like in the version of MoinMoin (1.5) we're using, the GUI editor reads in carriage returns to display everything correctly, but then only keeps HTML/macro line breaks. Definitely not a great moment in usability: http://moinmo.in/MoinMoinBugs/GuiEditorLineBreak. I think the reason the preview cuts off at the IRC section is because IRC logs have their own parser that especially freaks out when it can't find newlines. That's when the preview function throws in the towel.
For a moment I worried it was something to do with our CSS white-space settings in "pre" blocks, but we definitely have it set to keep line breaks. So long story short, it looks like as long as we're on MoinMoin v1.5, we're stuck with either the text editor or having to redo every line break in the GUI. I don't know if Dimi Paun's subscribed to this report with a current email address, but he's the one to contact about upgrading MoinMoin.
