Well, I must admit I didn't consider this carefully enough when I needed
it and constructed a replacement. I personally would prefer option b)
to a), that is: I would prefer a distorted + sign to an egg-shaped circle.
However, the logical solution would probably be a circled \pm or + rather
than an \opm similar to \oplus. As a replacement I used the \copyright
circle but that wasn't really the right size. A generic circle, just big
enough to contain \pm or + might be the best solution. That means option c).
