fileset: use decorator to mark a function as fileset predicate

Using decorator can localize changes for adding (or removing) a
fileset predicate function in source code.

It is also useful to pick predicates up for specific purpose. For
example, subsequent patches marks predicates as "call status" or "use
existing" via decorator.

To avoid (1) redundancy between "predicate name" and (the beginning
of) help document, and (2) accidental typo of help document, this
patch also makes decorator put predicate declration into the beginning
of help.
