Well, there are expansion conditions. If "condition" would accept
expansion conditions without surrounding "if" besides expanded strings,
we would get rid of one level of braces and possibly avoid backslashes
as well. The result would be much more readable.

At first sight, the first sets of expansion conditions and expanded
strings do not have common elements, but I may be wrong there. I was
never particularly good at guessing first sets. ;-)
