You can overcome many of the foibles of the forum editor by clicking the "Source" button at the top of the editor screen. It occasionally works correctly on the first try posting something but it pretty much always scrambles everything if you try to go back and edit a post. (I see now it did the same to me on a line.
(edit)
But I was able to correct it by inserting the messed up lines into code brackets. If you don't click the source button the editor will strip the indenting out of your code, and do other things to it as well, (such as strip the bracketed text.)
