INSTALL_MASK: index patterns anchored with leading slash (bug 675826)
For scalability, use a tree structure to index patterns that are
anchored with a leading slash.
Patterns anchored with leading slash are indexed by leading non-glob
components, making it possible to minimize the number of fnmatch
calls. For example:
/foo*/bar -> {'.': ['/foo*/bar']}
/foo/bar* -> {'foo': {'.': ['/foo/bar*']}}
/foo/bar/ -> {'foo': {'bar': {'.': ['/foo/bar/']}}}
