Where did you run across this?

Once upon a time, the compound assignments were specified as =+ and =-. This form was described as obsolete in 1978, so we're talking about ancient history. If you encountered this construction in 40-year-old C code then maybe the intended functionality was equivalent to:

Expand|Select|Wrap|Line Numbers

c -= -2;

If you encountered this construction in more recent code then it is merely a mistake.
