The example "a" + "b" was, of course, an example. Something like
"some really long string (probably longer than this one) that I " +
"can't quite fit onto one line in good conscience"
would be more realistic. There's also the case where code is
generated by another tool. Somewhat relatedly, I've seen C macros
that generate expressions like
1 + 1 + 1 + 1 + 1 + 1 + 0
so there are instances where this sort of thing comes up.
