--- Comment #4 from Dan Myers heron@xnapid.com 2009-12-14 17:00:16 --- I've confirmed that this does occur in Windows in the latest version of EditPlus (3.12 build 531), so this is not a bug in wine.
I'll also echo Bartosz Brachaczek in the comment above me - it's not actually a bug at all; the syntax highlighter is behaving properly, because in C/C++ it's not valid to put an actual newline inside a quoted string like that.
If you try the same thing in something like gedit, you'll see exactly the same behavior.
