Nevertheless, it is.  Maybe not so much unintentional, as made
unavoidable by the prior constraint that zstyle be a generic lookup
mechanism rather than be tightly coupled to the semantics of
completion contexts.

You're correct, it could.  But "matcher-list" also has to match, and
THAT only happens in one of those three cases, so there's no need to
constrain the pattern any further (unless you WANT to; refer to my
car-cover analogy).
