[copy] filter is applied to directories, even though docs say it's just applied to files #843

Hence I can't use a filter like file => file.endsWith('.js') because that excludes directories that don't end with .js.

The docs only mention files:

filter : Function to filter copied files. Return true to include, false to exclude. Can also return a Promise that resolves to true or false (or pass in an async function).

However when I log what the filter gets called with, it gets called with directories.

Ah, yeah; docs aren't well-written here. Calling with directories is intended behavior, but docs should reflect that. PR welcome to clarify docs. Also CC @manidlou

okay, I'll also make a separate issue about passing isDirectory to the filter, since I'm pretty sure copy already knows that so it would be a waste for the filter function to have to stat the path.
