wild-pathname-p

(wild-pathname-p pathname &optional field-key)

Whether the pathname carries a wildcard. With no field-key (or nil) it answers true when ANY component is wild; with one of :directory, :name or :type it tests just that component, and :host / :device / :version are always nil because those components do not exist (pathname-host).

A component is wild when it holds a * (any run of characters) or a ? (one character) -- the same wildcards directory matches with, so this predicate and that matcher cannot disagree. A ** directory component (:wild-inferiors, any number of levels) is wild by that same rule.

An unknown field key signals.

All four backends -- one definition in rontolisp source over primitives every backend has.
