Actually those are not typos.  In mathematics, "iff" is widely
understand to mean "if and only if".

I guess this brings up a good point though: We should not assume that
readers of the Guile manual are familiar with this terminology.

I'm leaving this bug open as a reminder that occurrences of "iff" should
probably be changed to something else.

Thanks for the report!
