Argh, I had not realized the quote around the whole ${if part was
necessary. Maybe some explicit examples of this stuff should be included
in the filter docs (or the filter part of the FAQ); I had looked but
couldn't find anything similar to what I wanted. Once I've got my
filter working, I'll post it for possible inclusion in the FAQ.
Thanks!
