As it would if you passed cs:full to cs-filter, which I am surmising would
be the simple and portable I-dont-want-to-limit-myself-to-7bit option. And
if you specify cs:ascii to pred->cs, it will work just as you want cs-filter
to work. pred->cs is just cs-filter with different default parameters.

cs-filter must start from some specified cs; my fear (and experience) is
that a client will explicitly code cs:ascii instead of cs:letter+digit, or
the appropriate union of more specific charsets. I don't want to lock out
the Latin-1 chars by default.
With lazy filtering, I was also hoping to avoid redundantly reflecting the
system Unicode character table within the Scheme image. Given the presence
of iterators and cs->list, perhaps this is futile. You have the advantage
over me of having actually implemented this SRFI.
Whatever is decided, as long as we don't call pred 2**16 times by default,
I'm happier than otherwise. I'm done.
