The string which matches [^+] is the newline of line 2. Emacs regex
negated classes will include newline unless you explicitly exclude it.
The regex [^+\n] matches what you'd express as [^+] in grep. Since
grep is line-oriented, but Emacs is buffer-oriented, this distinction
makes sense.
Furthermore, there is nowhere any assertion that occur and grep should
match exactly the same things -- there are numerous other differences,
all of which are hopefully adequately documented.
