One issue concerns the behavior of Ctrl-K, which deletes to the next CR/LF. If you are editing in a paragraph consisting of a single long line comprising numerous sentences, Ctrl-K in a Cocoa app like TeXShop deletes from the cursor to the end of the entire paragraph, and as far as I know there isn't anything like Emacs' Meta-K ("kill-sentence") that enables one to delete smaller chunks. With a fixed maximum line length ending in a CR/LF, you have finer-grained control over the effects of Ctrl-K. Whether or not that it is important or useful to anyone is of course a matter of personal preferences and style but (because I'm sure everyone wants to know :-) I prefer to move my hands out of standard typing position (e.g., to highlight text use arrow keys or the mouse) as little as possible, so for me this behavior is, if perhaps not exactly compelling, very useful.
