I made another draft based on a single callable argument to try out:
http://bugs.python.org/file10073/shutil.copytree.filtering.patch

The callable takes the src directory + its content as a list, and
returns filter eligible for exclusion

That makes me wonder, like Alexander said on the bug tracker:
In the glob-style patterns callable, do we want to deal with absolute paths ?
