Since July 20 it seems newline characters are no longer processed correctly in comments. In the past a single newline would allow another line to be shown directly below the previous line. That is useful when showing a list in a comment. Now a single newline is ignored and all subsequent text is treated as one long wrap-around line. New paragraphs still work because two consecutive newlines are used to delineate them. But such formatting is not desirable for lists because of the gratuitous vertical spacing.
The problem also has retroactively affected the appearance of all comments in my profile. Comments in my profile now exhibit the anomalous newline behavior. This makes sense because the profile is dynamically regenerated as more comments are created. I wrote comments on July 20 and July 21 so this anomalous newline processing would necessarily corrupt previous comments in my profile. Interestingly if I click through on a corrupt comment in my profile it often looks OK on the article. This is especially true on older articles where no new comment activity has taken place. That might have something to do with web server page caching. An older web page might have been processed and cached prior to the newline anomaly.
I'm not sure what the underlying problem is but I'd sure like to have this fixed. Many of my comments have a list of "Related Links" at the bottom. Those links and descriptions now look like crap.
