Cannot insert a `=` before a `=` without surrounding it with spaces

[nordlow]

If you, for instance, want to change a != to a == be replace ! with a = electric-operator-mode will, incorrectly, insert source the prepending = with a space.

Hi, yeah at the moment electric operator only looks backwards for operators. I'm not sure, but I suspect that looking forwards as well might add a lot of complexity and make the UX worse in some cases. I'll have a think about it sometime 🙂
