When editing a post in source-mode here in the forums, long lines trail off to the right, so only a small portion is visible at any one time. This makes editing in source mode more difficult.
The cause is that white-space is set to "pre" on
.cke_source in "/plugins/CKEditor/skins/flat/editor.css". Setting it instead to "pre-wrap" fixes this issue by allowing long lines to wrap, but otherwise preserving white-space.
