How far do you want to go? Is "a  b + c" the same as "a(b) + c" or the
same as "a(b + c)"?

There's meant to be two spaces between "a" and "b" but I lost one of
them, twice, to my M-q reflex when writing the above paragraph. They
may or may not be there as I send this.

And I don't really want to know which it is. I prefer parentheses.
They are not nearly as fragile.
