Exclude items by shell pattern as well as by name

Patterns such as `.*` or `@*` are matched against an item's own name
with `fnmatch`, in the same places as excluded names: resolving a
tree, extending a watch to a directory that appears later, and
delivering events. Dependents that prune large trees can now skip
whole families of directories without listing each name.
