tree_entry_interesting(): fix depth limit with overlapping pathspecs
Suppose we have two pathspecs 'a' and 'a/b' (both are dirs) and depth limit 1. In current code, pathspecs are checked in input order. When 'a/b' is checked against pathspec 'a', it fails depth limit and therefore is excluded, although it should match 'a/b' pathspec. This patch reorders all pathspecs alphabetically, then teaches tree_entry_interesting() to check against the deepest pathspec first, so depth limit of a shallower pathspec won't affect a deeper one.
