b8eacd1364 filter: Reduce redundant path and pattern splitting
A single call to filter.List will split the path only once and also
split each search pattern only once and use it for both match and
childMatch.

92eb1cbffd filter: document recursive wildcards
Match/ChildMatch accept a ** pattern which is not noted in the doc
string, nor do any of the docs or tests specify whether the match is
greedy (i.e., can 'foo/**/bar' match paths with additional intermediate
bar directories?).

Add a note to the doc string and add test cases for greedy matches.

4a36993c19 Smarter filter when children won't match
This improves restore performance by several orders of magniture by not
going through the whole tree recursively when we can anticipate that no
match will ever occur.
