templatefuncs: specialize "no match" value of search() to allow % operation
If Python had Maybe or Option, the type of the search() result would be
Option<Mapping>, which can be considered as a 0/1 container of a Mapping.
So it makes sense that {search(r'no match pattern', x) % "whatever"} is
mapped to an empty string.
